+# @(#)africa	7.7
+
+# This data is by no means authoritative; if you think you know better,
+# go ahead and edit the file (and please send any changes to
+# tz@elsie.nci.nih.gov for general use in the future).
+
+# From Paul Eggert <eggert@twinsun.com> (November 18, 1993):
+#
+# A good source for time zone historical data outside the U.S. is
+# Thomas G. Shanks, The International Atlas (3rd edition),
+# San Diego: ACS Publications, Inc. (1991).
+# Except where otherwise noted, it is the source for the data below.
+#
+# Another source occasionally used is Edward W. Whitman, World Time Differences,
+# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
+# I found in the UCLA library.
+#
+# A reliable and entertaining source about time zones is
+# Derek Howse, Greenwich time and the discovery of the longitude,
+# Oxford University Press (1980).
+#
+# I added so many Zone names that the old, mostly flat name space was unwieldy.
+# So I renamed the Zones to have the form AREA/LOCATION, where
+# AREA is the name of a continent or ocean, and
+# LOCATION is the name of a specific location within that region.
+# For example, the old zone name `Egypt' is now `Africa/Cairo'.
+#
+# Here are the general rules I used for choosing location names,
+# in decreasing order of importance:
+#
+#	Use only valid Posix file names.  Use only Ascii letters, digits, `.',
+#		`-' and `_'.  Do not exceed 14 characters or start with `-'.
+#		E.g. prefer `Brunei' to `Bandar_Seri_Begawan'.
+#	Include at least one location per time zone rule set per country.
+#		One such location is enough.
+#	If a name is ambiguous, use a less ambiguous alternative;
+#		e.g. many cities are named San Jose and Georgetown, so
+#		prefer `Costa_Rica' to `San_Jose' and `Guyana' to `Georgetown'.
+#	Keep locations compact.  Use cities or small islands, not countries
+#		or regions, so that any future time zone changes do not split
+#		locations into different time zones.  E.g. prefer `Paris'
+#		to `France', since France has had multiple time zones.
+#	Use traditional English spelling, e.g. prefer `Rome' to `Roma', and
+#		prefer `Athens' to the true name (which uses Greek letters).
+#		The Posix file name restrictions encourage this rule.
+#	Use the most populous among locations in a country's time zone,
+#		e.g. prefer `Shanghai' to `Beijing'.  Among locations with
+#		similar populations, pick the best-known location,
+#		e.g. prefer `Rome' to `Milan'.
+#	Use the singular form, e.g. prefer `Canary' to `Canaries'.
+#	Omit common suffixes like `_Islands' and `_City', unless that
+#		would lead to ambiguity.  E.g. prefer `Cayman' to
+#		`Cayman_Islands' and `Guatemala' to `Guatemala_City',
+#		but prefer `Mexico_City' to `Mexico' because the country
+#		of Mexico has several time zones.
+#	Use `_' to represent a space.
+#	Omit `.' from abbreviations in names, e.g. prefer `St_Helena'
+#		to `St._Helena'.
+#
+# We typically use traditional English time zone abbreviations,
+# and assume that applications translate them to other languages
+# as part of the normal localization process.
+#
+# I made up the following time zone abbreviations; corrections are welcome!
+#		LMT	Local Mean Time
+#	-2:00	CVT	Cape Verde Time (no longer used)
+#	-1:00	AAT	Atlantic Africa Time
+#	 0:00	WAT	West Africa Time
+#	 1:00	CAT	Central Africa Time
+#	 2:00	SAT	South Africa Time
+#	 3:00	EAT	East Africa Time
+#	 4:00	SMT	Seychelles and Mascarene Time
+# The final `T' is replaced by `ST' for summer time, e.g. `SAST'.
+# BEAT is British East Africa Time, which was 2:30 before 1948 and 2:45 after.

+# People's Republic of China.  Yes, they really have only one time zone.
+
+# From Bob Devine (January 28, 1988):
+# No they don't.  See TIME mag, February 17, 1986 p.52.  Even though
+# China is across 4 physical time zones, before Feb 1, 1986 only the
+# Peking (Bejing) time zone was recognized.  Since that date, China
+# has two of 'em -- Peking's and Urumqi (named after the capital of
+# the Xinjiang Uighur Autonomous Region).  I don't know about DST for it.
+#
+# . . .I just deleted the DST table and this editor makes it too
+# painful to suck in another copy..  So, here is what I have for
+# DST start/end dates for Peking's time zone (info from AP):
+#
+#     1986 May 4 - Sept 14
+#     1987 mid-April - ??
+
+# From Paul Eggert <eggert@twinsun.com> (November 18, 1993):
+# According to Shanks, China started using DST in 1986,
+# but it's still all one big happy time zone.
+
+# From U. S. Naval Observatory (January 19, 1989):
+# CHINA               8 H  AHEAD OF UTC  ALL OF CHINA, INCL TAIWAN
+# CHINA               9 H  AHEAD OF UTC  APR 17 - SEP 10
+
+# From Paul Eggert <eggert@twinsun.com> (November 18, 1993):
+# Shanks writes that China switched from the Chinese calendar on 1912 Feb 12.
+# He also writes that China has had a single time zone since 1980 May 1,
+# and that they instituted DST on 1986 May 4; this contradicts Devine's

+# Each year they decide anew what havoc to wreak on the country.  However,
+# there is a "supposed" set of rules which is subject to change depending
+# on the party the Minister of Interior, the size of the coalition
+# government, the phase of the moon and the direction of the wind.  Hence,
+# changes may need to be made on a semi-annual basis.  One thing is entrenched
+# in law, however: that there must be at least 150 days of daylight savings
+# time annually.  Ever since 1993, the change to daylight savings time has
+# been from midnight Thursday night to 1 a.m. Friday morning and the change
+# back to standard time on Saturday night from midnight daylight savings time

+# Australia
+
+# From John Mackin (March 6, 1991):
+# We in Australia have _never_ referred to DST as `daylight' time.
+# It is called `summer' time.  Now by a happy coincidence, `summer'
+# and `standard' happen to start with the same letter; hence, the
+# abbreviation does _not_ change...
+# The legislation does not actually define abbreviations, at least
+# in this State, but the abbreviation is just commonly taken to be the
+# initials of the phrase, and the legislation here uniformly uses
+# the phrase `summer time' and does not use the phrase `daylight
+# time'.
+# Announcers on the Commonwealth radio network, the ABC (for Australian
+# Broadcasting Commission), use the phrases `Eastern Standard Time'
+# or `Eastern Summer Time'.  (Note, though, that as I say in the
+# current australasia file, there is really no such thing.)  Announcers
+# on its overseas service, Radio Australia, use the same phrases
+# prefixed by the word `Australian' when referring to local times;
+# time announcements on that service, naturally enough, are made in UTC.
+
+# From Arthur David Olson (March 8 1992):
+# Given the above, what's chosen for year-round use is:
+#	CST	for any place operating at a GMTOFF of 9:30
+#	WST	for any place operating at a GMTOFF of 8:00
+#	EST	for any place operating at a GMTOFF of 10:00
+
+# From Paul Eggert (November 8, 1994):
+# Shanks reports 2:00 for all autumn changes in Australia and New Zealand.
+# Mark Prior <mrp@itd.adelaide.edu.au> writes that his newspaper
+# reports that NSW's fall 1995 change will occur at 2:00,
+# but Robert Elz says it's been 3:00 in Victoria since 1970
+# and perhaps the newspaper's `2:00' is referring to standard time.
+# And Robert Uzgalis <buz@cs.aukuni.ac.nz> says that the New Zealand Daylight
+# Savings Time Order in Council dated 1990-06-18 specifies 2:00 standard
+# time on both the first Sunday in October and the third Sunday in March.
+# For now we'll continue to assume 3:00 for changes since 1970.

+
+# From Peter Ilieve <peter@memex.co.uk> (July 6, 1994):
+#
+# On 17 Jan 1994 the Independent, a UK quality newspaper, had a piece about
+# historical vistas along the Thames in west London. There was a photo
+# and a sketch map showing some of the sightlines involved. One paragraph
+# of the text said:
+#
+# `An old stone obelisk marking a forgotten terrestrial meridian stands
+# beside the river at Kew. In the 18th century, before time and longditude
+# was standardised by the Royal Observatory in Greenwich, scholars observed
+# this stone and the movement of stars from Kew Observatory nearby. They
+# made their calculations and set the time for the Horse Guards and Parliament,
+# but now the stone is obscured by scrubwood and can only be seen by walking
+# along the towpath within a few yards of it.'
+#
+# I have a one inch to one mile map of London and my estimate of the stone's
+# position is 51 deg. 28' 30" N, 0 deg. 18' 45" W. The longditude should
+# be within about +-2". The Ordnance Survey grid reference is TQ172761.
+#
+# [This yields GMTOFF = -0:01:15 for London LMT in the 18th century.]
+
+# From Paul Eggert <eggert@twinsun.com> (November 18, 1993):
+#
+# Howse writes that Britain was the first country to use standard time.
+# The railways cared most about the inconsistencies of local mean time,
+# and it was they who forced a uniform time on the country.
+# The original idea was credited to Dr. William Hyde Wollaston (1766-1828);
+# it was popularized in 1840 by Capt. Basil Hall, RN (1788-1844),
+# famed explorer and former Commissioner for Longitude.
+# The first railway to adopt London time was the Great Western Railway
+# in November 1840; other railways followed suit, and by 1847 most
+# (though not all) railways used London time.  On 1847 Sep 22 the
+# Railway Clearing House, an industry standards body, recommended that GMT be
+# adopted at all stations; the January 1848 Bradshaw's lists most major
+# railways as using GMT.  By 1855 the vast majority of public
+# clocks in Britain were set to GMT (though some, like the Great Clock
+# in Tom Tower at Christ Church, Oxford, were fitted with two minute hands,
+# one for local time and one for GMT).  The last major holdout was the legal
+# system, which stubbornly stuck to local time for many years, leading
+# to oddities like polls opening at 08:13 and closing at 16:13.
+# The legal system finally switched to GMT when the Statutes (Definition
+# of Time) Act took effect; it received the Royal Assent on 1880 Aug 2.
+#
+# In the tables below, we condense this complicated story into a single
+# transition date for London, namely 1847 Sep 22.  We don't know as much
+# about Dublin, so we use 1880 Aug 2, the legal transition time.
+
+# From Arthur David Olson (January 19, 1989):
+#
+# A source at the British Information Office in New York avers that it's
+# known as "British" Summer Time in all parts of the United Kingdom.
+
+# Date: 4 Jan 89 08:57:25 GMT (Wed)
+# From: Jonathan Leffler <nih-csl!uunet!mcvax!sphinx.co.uk!john>
+# [British Summer Time] is fixed annually by Act of Parliament.
+# If you can predict what Parliament will do, you should be in
+# politics making a fortune, not computing.
+
+# From Peter Ilieve <peter@memex.co.uk> (September 3, 1993):
+#
+# Our Government...couldn't...make a decision after the 1989 consultation
+# exercise about the UK changing its timezone so it just let things drift
+# (different from deciding to keep the status quo).  According to the
+# Summer Time Order 1992 (SI 1992/1729) the dates of Summer Time for 1993
+# and 1994 are:
+#	Start		End
+# 1993	28 March	24 October
+# 1994	27 March	23 October
+# All start and end times are at 01:00 GMT.
+#
+# There [was] an error in your tables for the start and end times prior to 1981.
+# The UK always used to change at 02:00 GMT. In 1981 it changed to 01:00 GMT
+# as a part of EC harmonisation and has remained at that time since.
+#
+# I have found the default algorithm for UK Summer Time, it is in the
+# Summer Time Act 1972. Section 1 states that in the absence of an Order
+# in Council Summer Time starts at 02:00 GMT on the morning of the day
+# after the third Saturday in March, unless that day is Easter Day, in
+# which case it is the morning of the day after the second Saturday.
+# It ends at 02:00 GMT on the morning of the day after the fourth Saturday
+# in October. (All the redundant `morning of the day ...' is in the Act.)
+# This is only of passing interest now as it will always be overridden by
+# an Order in Council (a Statutary Instrument, the SI thing mentioned above)
+# to specify the EC specified dates.
+
+# From Peter Ilieve <peter@memex.co.uk> (October 18, 1993):
+#
+# My contact in the Ministry of Defence Public Relations department
+# accepted the challenge of looking into this and produced the following,
+# from Hansard (the official record of the UK Parliament), Oral Answers,
+# 1 March 1945, cols 1559--60:
+#
+# `58. Major Sir Goronwy Owen asked the Secretary of State for the Home
+# Department if he is now able to state the Government's proposals
+# regarding double summer time.
+#
+# [two other similar questions omitted]
+#
+# Mr. H. Morrison: The Government, in reviewing the matter, have
+# considered, [...] the conclusion has been reached that the adoption of
+# double summer time from the beginning of April is essential to the
+# maintenance of the war effort. [...] As 1st April is Easter Sunday,
+# when very early services are held in many churches, it is proposed that
+# double summer time shall start not in the night preceding Easter
+# Sunday, but in the night of Sunday- Monday so that it will operate from
+# Monday, 2nd April.'
+
+# From Peter Ilieve <peter@memex.co.uk> (September 3, 1993):
+#
+# > # Current rules
+# > Rule GB-Eire 1981	max	-	Mar	lastSun	1:00s	1:00	BST
+# > Rule GB-Eire 1981	max	-	Oct	Sun>=23	1:00s	0	GMT
+#
+# The ending rule here doesn't match the EC rules, which specify the fourth
+# Sunday in October for the UK and Eire. The `fourth Sunday' rule wasn't
+# followed in 1989, but then the sixth EC directive wasn't in force then
+# and I don't know what previous ones said. 1995 is the next year with
+# the 4th Sun on 22 Oct, but that year isn't covered by the UK Summer Time
+# Order or the sixth EC directive. Your Oct Sun>=23 rule matches history
+# and with things only announced for 2 years or so in advance who knows
+# what will happen.
+#
+# There are renewed rumours that the Government here will make another
+# attempt at resolving this issue, which is what prompted me to start
+# asking the Home Office and the EC about it again. The EC categorically
+# state they are not asking anybody to change timezone, they only want
+# common start/end dates. The UK Govt. seem to want to change our zone
+# and blame the resulting fuss on the EC. Me, I think we should scrap
+# summer time completely, noon is when the Sun is overhead, and that should
+# be the end of it.
+
+# From Peter Ilieve <peter@memex.co.uk> (October 22, 1993):
+#
+# I now have the text of the Summer Time Act 1916, the granddaddy of them all.
+# It is headed: `An Act to provide for the Time in Great Britain and Ireland
+# being in advance of Greenwich and Dublin mean time respectively in the
+# summer months'.
+#
+# It specifies 21 May and 1 October for 1916 (both at 02:00 GMT) and whatever
+# dates an Order in Council may specify for subsequent years.
+#
+# Section 4 states: `This act shall apply to Ireland in like manner as it
+# applies to Great Britain, with the substitution however of references
+# to Dublin mean time for references to Greenwich mean time.'
+#
+# Lorna, my learned legal friend who supplied it, also offers this quote
+# from Halsbury's Statutes on the extent of Acts:
+#
+# `An Act of the United Kingdom Parliament is to be construed prima facie
+# to apply to the whole of the United Kingdom and not to any place outside.
+# [...] The expression "United Kingdom" for this purpose includes (since
+# 1922) Great Britain (ie. England, Wales and Scotland) and Northern Ireland,
+# but it does not include the Channel Islands or the Isle of Man.'
+#
+# She goes on to say the seminal event of 1922 was the establishment of
+# the Irish Free State, now called Eire.
+#
+# The Act doesn't say anything about Wales (or Scotland) so I would assert
+# that Shanks is wrong here. I would like to know why he thinks Wales
+# was different.
+#
+# It also confirms the fact that Ireland followed Dublin time back then,
+# and 25 minutes behind Greenwich, as Shanks has it, would be correct.
+
+# From Peter Ilieve <peter@memex.co.uk> (October 28, 1993):
+#
+# I now have before me, thanks to my learned legal friend Lorna, the text of
+# the Time (Ireland) Act 1916.
+#
+# It says that as from 2 AM Dublin Mean Time on 1 October 1916 the time
+# for general purposes in Ireland shall be the same as the rest of Great
+# Britain (ie. GMT with the Summer Time periods specified by the Summer Time
+# Act 1916)....  As Ireland was behind GMT/BST at 02:00 DMT on 1 Oct GB would
+# have already put the clocks back. Using DST as Dublin Summer Time the
+# sequence would have been:
+# Dublin		London
+# 02:34 DST	02:59 BST
+# 02:35 DST	02:00 GMT
+# 02:59 DST	02:24 GMT
+# 02:25 GMT	02:25 GMT
+# with the transition 03:00 DST -> 02:00 DMT -> 02:25 GMT all at once.
+#
+# In a table of repeals in the Schedule to the Act it mentions the
+# Statutes (Definition of Time) Act 1880. This is presumably the source
+# of the 1880 date in Shanks.  The little bit of it that is repealed
+# also refers solely to Ireland and Dublin Mean Time.
+
+# From Peter Ilieve <peter@memex.co.uk> (October 29, 1993):
+#
+# My case is that, with the sole exception of Ireland in 1916 using Dublin
+# Mean Time, Summer Time has been uniform throughout the United Kingdom
+# ever since it first started in 1916.
+#
+# The United Kingdom is England, Wales and Scotland plus all of Ireland from
+# 1916 up to and including 1921, or plus Northern Ireland from 1922 to date.
+#
+# The dates used are those specified in the table in Summer Time: A Consultation
+# Document (Cm 722, 1989) that are now included in the europe file, with a
+# change to a single date, the start in 1924. I made a typo in my 1989 mail
+# and the table itself is also wrong.  The correct date is 13 April.
+# The times were 02:00 GMT up to and including 1980, 01:00 GMT from 1981 on,
+# except for wartime double summer time.
+#
+# As evidence I would cite:
+#
+# - The Summer Time Act, 1916.
+#
+# This specifically states that it applies to Ireland, specifies dates of
+# 21 May and 1 October and times of 02:00, and says that in Ireland the
+# times relate to Dublin mean time. It specifies an offset of 1 hour.
+#
+# - The Time (Ireland) Act, 1916
+#
+# This abolishes Dublin mean time on 02:00 DMT 1 October 1916.
+# It repeals that section of the Statutes (Definition of Time) Act, 1880
+# that specifies DMT. It is therefore a safe bet that DMT existed at least
+# from 1880 and was the only alternative standard time in the UK.
+#
+# - The Summer Time Act, 1922
+#
+# This specifies an offset of 1 hour and dates of the day after the third
+# Saturday in April, unless that be Easter, in which case it is the day after
+# the second Saturday, and the day after the third Saturday in September.
+# The time is 02:00 GMT. It applied in 1922 and 1923, and longer if Parliament
+# so approved.
+#
+# It specifically states that it applies to Northern Ireland, the Channel
+# Islands, and the Isle of Man.
+#
+# - The Summer Time Act, 1925
+#
+# This makes the 1922 Act permanent, with a change to the end date to the
+# day after the first Saturday in October. It says nothing about extent,
+# so that part of the 1922 Act will still apply.
+#
+# - The Defence (Summer Time) Regulations, 1939, SR&O 1939 No. 1379
+#   [SR&O == Statutary Regulation and Order]
+#
+# These were made under the Emergency Powers (Defence) Act, 1939.
+# It changes the end date to be the day after the third Saturday in November.
+# It makes consequential changes to some vehicle lighting legislation,
+# which includes the Motor Vehicles and Road Traffic (Northern Ireland) Act,
+# 1934, so it seems clear it applies in Northern Ireland.
+#
+# - An Order in Council amending the The Defence (Summer Time) Regulations,
+#   1939, SR&O 1940 No. 1883
+#
+# This continues summer time throughout the year after it starts in 1940.
+# It says nothing about extent and has no consequential changes.
+#
+# - An Order in Council amending the The Defence (Summer Time) Regulations,
+#   1939, SR&O 1941 No. 476
+#
+# This introduces double summer time, starting at 01:00 GMT on the day after
+# the first Saturday in May and ending at 01:00 GMT on the day after the
+# second Saturday in August, offset another hour from normal summer time,
+# which continues throughout the rest of the year. It goes on a lot about
+# consequential changes to agricultural wages legislation, and says in part
+# `... and in its application to Northern Ireland have effect as
+# if for the references to the Agricultural Wages (Regulation) Acts, 1924 and
+# 1940, there were substituted references to the Agricultural Wages (Regulation)
+# Acts (Northern Ireland), 1939 and 1940, ...'. It also has a similar section
+# for Scotland. Both sections substitute the local Agricultural Wages Board
+# for the Agricultural Wages Board for England and Wales, showing that
+# England and Wales were indivisible.
+#
+# - An Order in Council amending the The Defence (Summer Time) Regulations,
+#   1939, SR&O 1942 No. 506
+#
+# This changes the start date of double summer time to the day after the first
+# Saturday in April. It says nothing about extent.
+#
+# - An Order in Council amending the The Defence (Summer Time) Regulations,
+#   1939, SR&O 1944 No. 932
+#
+# This changed the end date of double summer time to 17 September 1944.
+# (I don't have the text of this, just a note of what it did, the text almost
+# certainly had the `day after the nth Saturday' form.)
+#
+# (I am missing whatever regulations there were to change things in 1945
+# and the Summer Time Act, 1947.)
+#
+# - The British Standard Time Act, 1968
+#
+# This came into force on 27 October 1968 and continued summer time throughout
+# the year as an experiment until it expired on 31 October 1971.
+# There was no double summer time so we didn't have to change the clocks at all.
+# It specifically said it applied to Northern Ireland. It also said it
+# applied to Jersey, Guernsey and the Isle of Man unless they passed
+# measures saying it didn't.
+#
+# - The Manx Time Act, 1968
+#
+# This is an Act of Tynwald (the Isle of Man Parliament) that said that
+# henceforth Manx time would be the same as the time in Great Britain.
+#
+# - The Summer Time Act, 1972
+#
+# This specified a reversion to normal summer time behaviour with a start
+# date of the day after the third Saturday in March, unless that is Easter,
+# when it is the day after the second Saturday, and an end date of the day
+# after the fourth Saturday in October. Times are at 02:00 GMT, offset is
+# 1 hour.
+#
+# It has the same wording about extent as the British Standard Time Act, 1968,
+# applying to Northern Ireland unconditionally and to Jersey, Guernsey and the
+# Isle of Man if they don't do something about it.
+#
+# (I am missing various Summer Time Orders that modified the 1972 Act to
+# harmonise with the EC since 1981. The major change is that the time changes
+# to 01:00 GMT.)
+#
+# - The Summer Time Order, 1992, SI 1992/1729 [SI == Statutary Instrument]
+#
+# This specifies dates of:
+#       Start       End
+# 1993  28 March    24 October
+# 1994  27 March    23 October
+# All start and end times are at 01:00 GMT....
+#
+# - Some text on the extent of Acts, from Halsbury's Statutes
+#
+# `An Act of the United Kingdom Parliament is to be construed prima facie
+# to apply to the whole of the United Kingdom and not to any place outside.
+# [...] The expression "United Kingdom" for this purpose includes (since
+# 1922) Great Britain (ie. England, Wales and Scotland) and Northern Ireland,
+# but it does not include the Channel Islands or the Isle of Man.'
+#
+# So, many of these measures specifically include Northern Ireland,
+# the Channel Islands and the Isle of Man. None of them exclude any
+# part of the UK. The default interpretation of Acts is that they apply
+# throughout the UK.
+#
+# With that, I rest my case Milud :-)
+#
+# Thanks are due to my learned legal friend Lorna Montgomerie, who dug out
+# the dusty old statutes, and to Melanie Allison of the Ministry of Defence,
+# who provided the wartime regulations and a snippet of Hansard explaining
+# why double summer time started on a Monday in 1945 (it was Easter).
+
+# From Peter Ilieve <peter@memex.co.uk> (November 18, 1993)
+#
+# Here is a revised version of my tabrules file for the perl script I sent
+# before. I have personally verified the various Orders back to 1953 and
+# all the Acts.
+#
+# There are no changes to the dates we already have.
+#
+# My doubt about an early start in 1967 on 18 Feb was misplaced, the Order
+# does say 18 Feb. This is an interesting case as the first Order gave a
+# different date of 7 April 1967 for the Isle of Man but this was changed
+# before it came into effect by another Order for the Isle of Man alone.
+#
+# I don't think I will be able to find any more of the earlier Orders.
+# The annual volumes for 1949--52 do not contain the various Summer Time
+# Orders. They therefore don't appear in the index. They rate a mention in
+# italics in the numerical list at the start but that is all.
+# I think what happens is that the annual volume is produced well after the
+# end of the year in question, by which time the Summer Time Order is spent.
+# They assume that nobody would ever be stupid enough to want to see it
+# again so they leave it out.
+#
+# It might be a good idea to put this table, or the output of tabscript
+# showing all the moves because of Easter, in the europe file comments in
+# place of my old transcription of the Green Paper table [the UK Government
+# paper "Summer Time: A Consultation Document" (HMSO Cm722 June 1989)].

+# From Peter Ilieve <peter@memex.co.uk> (August 18, 1994):
+# I now have the text of the 7th EC directive on summer time arrangements
+# (94/21/EC), which was approved on 30 May....
+# The major changes from existing practice are that 1995 will be the last year
+# that the UK and Eire finish on a different date from everyone else,
+# and the common end date from 1996 onwards will be the last Sunday in October.
+# Year	 Start		End		End (UK & Eire, 1995 only)
+# (rule) (last Sun)	(last Sun)	(4th Sun)
+# 1995	26 March	24 September	22 October
+# 1996	31 March	27 October
+# 1997	30 March	26 October
+#
+# From Peter Ilieve <peter@memex.co.uk> (1994-12-01):
+# The final piece of the legislative jigsaw for summer time in the UK for
+# 1995-97 is now in place.  The Summer Time Order 1994 (SI 1994/2798)
+# came into force on 16 November.  It restates the dates from the EC
+# seventh Summer Time Directive....
+
+# From Peter Ilieve <peter@memex.co.uk> (March 28, 1994):
+# The UK/Eire end date of 22 October [1995] conflicts with your current rule of
+# Oct Sun>=23, and the historical UK formula of Sun after 4th Sat.
+# The last time 4th Sun and Sun after 4th Sat differed was in 1989,
+# when 29 October was used.  That year was covered by a UK Summer Time Order
+# for only a single year and it looks as though there was a matching 4th EC
+# directive for just this year.  I don't have the text of the 5th EC
+# directive (for 1990--92) but my guess would be it said 4th Sun.
+# To maintain strict historical accuracy you could start a new UK ending rule
+# of Oct Sun>=22 in 1990.
+
+# From Paul Eggert <eggert@twinsun.com> (November 18, 1993):
+#
+# As Ilieve remarks, the date `20 April 1924' in the table of ``Summer Time: A
+# Consultation Document'' (Cm 722, 1989) table is a transcription error;
+# 20 April was an Easter Sunday.  Shanks has 13 April, the correct date.
+# Also, the table is not quite right for 1925 through 1938; the correct rules
+# (which Shanks uses) are given in the Summer Time Acts of 1922 and 1925.
+# Shanks and the UK Government paper disagree about the Apr 1956 transition;
+# since we have no other data, and since Shanks was correct in the other
+# points of disagreement about London, we'll believe Shanks for now.
+# Also, for lack of other data, we'll follow Shanks for Eire in 1940-1948.
+#
+# Given Peter Ilieve's comments, the following claims by Shanks are incorrect:
+#     * Wales did not switch from GMT to daylight savings time until
+#	1921 Apr 3, when they began to conform with the rest of Great Britain.
+# Actually, Wales was identical after 1880.
+#     * Eire had two transitions on 1916 Oct 1.
+# It actually just had one transition.
+#     * Northern Ireland used single daylight savings time throughout WW II.
+# Actually, it conformed to Britain.
+#
+# The following claim by Shanks is possible though doubtful;
+# we'll ignore it for now.
+#     * Jersey, Guernsey, and the Isle of Man did not switch from GMT
+#	to daylight savings time until 1921 Apr 3, when they began to
+#	conform with Great Britain.
+#
+# Whitman says Dublin Mean Time was -0:25:21, which is more precise than Shanks.

+# Iceland
+#
+# From Adam David <adam@veda.is> (November 6, 1993):
+# The name of the timezone in Iceland for system / mail / news purposes is GMT.
+#
+# (December 5, 1993):
+# This material is paraphrased from the 1988 edition of the University of
+# Iceland Almanak.
+#
+# From January 1st, 1908 the whole of Iceland was standardised at 1 hour
+# behind GMT. Previously, local mean solar time was used in different parts
+# of Iceland, the almanak had been based on Reykjavik mean solar time which
+# was 1 hour and 28 minutes behind GMT.
+#
+# "first day of winter" referred to [below] means the first day of the 26 weeks
+# of winter, according to the old icelandic calendar that dates back to the
+# time the norsemen first settled Iceland.  The first day of winter is always
+# Saturday, but is not dependent on the Julian or Gregorian calendars.
+#
+# (December 10, 1993):
+# I have a reference from the Oxford Icelandic-English dictionary for the
+# beginning of winter, which ties it to the ecclesiastical calendar (and thus
+# to the julian/gregorian calendar) over the period in question.
+#	the winter begins on the Saturday next before St. Luke's day
+#	(old style), or on St. Luke's day, if a Saturday.
+# St. Luke's day ought to be traceable from ecclesiastical sources. "old style"
+# might be a reference to the Julian calendar as opposed to Gregorian, or it
+# might mean something else (???). The Gregorian calendar was not introduced
+# in Iceland until 1700.
+#
+# From Paul Eggert <eggert@twinsun.com> (December 9, 1993):
+# The Iceland Almanak, Shanks and Whitman disagree on many points.
+# We go with the Almanak, except for one claim from Shanks, namely that
+# Reykavik was -1:28 from 1837 to 1908, local mean time before that.

+# The information from Tom Hofmann is (as far as I know) not entirely correct.
+# After a request from chongo at amdahl I tried to retrieve all information
+# about DST in Europe.  I was able to find all from about 1969.
+#
+# ...standardization on DST in Europe started in about 1977 with switches on
+# first Sunday in April and last Sunday in September...
+# In 1981 UK joined Europe insofar that
+# the starting day for both shifted to last Sunday in March.  And from 1982
+# the whole of Europe used DST, with switch dates April 1 and October 1 in
+# the Sov[i]et Union.  In 1985 the SU reverted to standard Europe[a]n switch
+# dates...
+#
+# It should also be remembered that time-zones are not constants; e.g.
+# Portugal switched in 1976 from MET (or CET) to WET with DST...
+# Note also that though there were rules for switch dates not
+# all countries abided to these dates, and many individual deviations
+# occurred, though not since 1982 I believe.  Another note: it is always
+# assumed that DST is 1 hour ahead of normal time, this need not be the
+# case; at least in the Netherlands there have been times when DST was 2 hours
+# in advance of normal time.

+# Turning to Europe, I now have a copy of the `Sixth Council Directive 92/20/EEC
+# of 26 March 1992 on summertime arrangements'. This only covers 1993 and
+# 1994, a seventh one is in the works but I doubt that the algorithm will
+# change. This says summertime starts at 01:00 GMT on the last Sunday in March
+# and ends at 01:00 GMT on the last Sunday in September, except for the UK
+# and Eire where it ends at 01:00 GMT on the fourth Sunday in October.
+# It says the arrangements for 1995 onwards will be decided by 1 January 1994,
+# but as the sixth directive was supposed to appear by 1 Jan 92 and didn't
+# arrive til March I wouldn't hold your breath.
+#
+# The first summertime directive was adopted in 1980, although the UK didn't
+# seem to use it until 1981. I suspect it would be safe to move your start
+# dates for the -Eur rules back to 1981.

+
+# From W. Jones (jones@skdad.usask.ca) (November 6, 1992):
+# The. . .below is based on information I got from our law library, the
+# provincial archives, and the provincial Community Services department.
+# A precise history would require digging through newspaper archives, and
+# since you didn't say what you wanted, I didn't bother.
+#
+# Saskatchewan is split by a time zone meridian (105W) and over the years
+# the boundary became pretty ragged as communities near it reevaluated
+# their affiliations in one direction or the other.  In 1965 a provincial
+# referendum favoured legislating common time practices.
+#
+# On 15 April 1966 the Time Act (c. T-14, Revised Statutes of
+# Saskatchewan 1978) was proclaimed, and established that the eastern
+# part of Saskatchewan would use CST year round, that districts in
+# northwest Saskatchewan would by default follow CST but could opt to
+# follow Mountain Time rules (thus 1 hour difference in the winter and
+# zero in the summer), and that districts in southwest Saskatchewan would
+# by default follow MT but could opt to follow CST.
+#
+# It took a few years for the dust to settle (I know one story of a town
+# on one time zone having its school in another, such that a mom had to
+# serve her family lunch in two shifts), but presently it seems that only
+# a few towns on the border with Alberta (e.g. Lloydminster) follow MT
+# rules any more; all other districts appear to have used CST year round
+# since sometime in the 1960s.
+#
+# Here's how I would summarize things.  Establish a "Saskatchewan" CST
+# time zone, and note that it officially exists as of 15 April 1966.  Any
+# current exceptions can put themselves in the "Mountain" zone, since
+# those are the rules they follow.  Any past exceptions can be forgotten,
+# since that's what those who live here have done.
+
+# From Arthur David Olson (November 21, 1992):
+# East-Saskatchewan kept to avoid problems for folks using that zone by name;
+# plain Saskatchewan added.

+# Mexico
+
+# From Guy Harris:
+# Rules are from the Official Airline Guide, Worldwide Edition, for 1987.
+# Rules prior to 1987 are unknown.
+# The comments in the OAG say "Only Ensenada, Mexicale, San Felipe and Tijuana
+# observe DST."  This is presumably Baja California Norte, above 28th parallel,
+# as listed there; Mexico/BajaSur is for "Baja California Sur and N. Pacific
+# Coast (States of Sinaloa and Sonora)."
+
+# From Bob Devine (January 28, 1988):
+# The Federal District (where Mexico City is) has observed [DST] several
+# times but not recently.
+#
+# I don't where to drawn the line in the North Baja area.  28th latitude
+# sounds good -- but it may be higher (how far [d]o radio stations from
+# San Diego affect culture?).
+#
+# The dates of DST probably go back to 1981.  The rules are the same as
+# US's.  This is going to be a headache for US presidential electi[o]n years!
+
+# From Arthur David Olson (February 13, 1988)
+# Since the 1981 starting date is only "probable," we'll keep the 1987
+# starting date below.
+
+# From U. S. Naval Observatory (January 19, 1989):
+# MEXICO BAJA CAL N   7 H  BEHIND UTC    BAJA CALIFORNIA SUR AND
+# MEXICO BAJA CAL N                      N. PACIFIC COAST (STATES
+# MEXICO BAJA CAL N                      OF SINALOA AND SONORA)
+# MEXICO BAJA CAL N   8 H  BEHIND UTC    ABOVE 28TH PARALLAL APR 3

+# MEXICO                                 YUCATAN
+
+# From Arthur David Olson (January 21, 1989):
+# April 3 fell on a Sunday in 1988; October 29 fell on a Sunday in 1989.  Ahem.
+# USNO claims there should be four Mexican zones rather than three:
+# a zone that's GMT-8 with DST; a zone that's always GMT-7;
+# a zone that's GMT-6 with DST; and a zone that's always GMT-6.
+
+# From Paul Eggert <eggert@twinsun.com> (November 18, 1993):
+# Shanks also says there are four zones, but disagrees about the fourth.
+# Instead of GMT-6 with DST, he says there's GMT-8 without DST.

+# establishing "Pacific Presidential Election Time"; it was not acted on
+# by the Senate or signed into law by the President.
+# You might want to change the "PE" (Presidential Election) below to
+# "Q" (Quadrennial) to maintain three-character zone abbreviations.
+# If you're really conservative, you might want to change it to "D".
+# Avoid "L" (Leap Year), which won't be true in 2100.

+# Apparent noon times below are for Riyadh; they're a bit off for other places.
+# Times were computed using formulas in the U.S. Naval Observatory's
+# Almanac for Computers 1988; the formulas "will give EqT to an accuracy of
+# [plus or minus two] seconds during the current year."
+#
+# Rounding to the nearest five seconds results in fewer than
+# 256 different "time types"--a limit that's faced because time types are
+# stored on disk as unsigned chars.

+# Apparent noon times below are for Riyadh; they're a bit off for other places.
+# Times were computed using a formula provided by the U. S. Naval Observatory:
+#	eqt = -105.8 * sin(l) + 596.2 * sin(2 * l) + 4.4 * sin(3 * l)
+#		-12.7 * sin(4 * l) - 429.0 * cos(l) - 2.1 * cos (2 * l)
+#		+ 19.3 * cos(3 * l);
+# where l is the "mean longitude of the Sun" given by
+#	l = 279.642 degrees + 0.985647 * d
+# and d is the interval in days from January 0, 0 hours Universal Time
+# (equaling the day of the year plus the fraction of a day from zero hours).
+# The accuracy of the formula is plus or minus three seconds.
+#
+# Rounding to the nearest five seconds results in fewer than
+# 256 different "time types"--a limit that's faced because time types are
+# stored on disk as unsigned chars.
