+In this example, the zone is named Europe/Zurich but it has an alias

+as Switzerland. Zurich was 34 minutes and 8 seconds west of GMT until

+1848-09-12 at 00:00, when the offset changed to 29 minutes and 44

+seconds. After 1894-06-01 at 00:00 Swiss daylight saving rules (defined

+with lines beginning with "Rule Swiss") apply, and the GMT offset

+became one hour. From 1981 to the present, EU daylight saving rules have

+applied, and the UTC offset has remained at one hour.

+.Pp

+In 1940, daylight saving time applied from November 2 at 00:00 to

+December 31 at 00:00. In 1941 and 1942, daylight saving time applied

+from the first Sunday in May at 02:00 to the first Sunday in October

+at 00:00.

+The pre-1981 EU daylight-saving rules have no effect

+here, but are included for completeness. Since 1981, daylight

+saving has begun on the last Sunday in March at 01:00 UTC.

+Until 1995 it ended the last Sunday in September at 01:00 UTC,

+but this changed to the last Sunday in October starting in 1996.

+.Pp

+For purposes of

+display, "LMT" and "BMT" were initially used, respectively. Since

+Swiss rules and later EU rules were applied, the display name for the

+timezone has been CET for standard time and CEST for daylight saving

+time.
