Based on a patch from enh@google. OK tb@

Explicitly mention that most programs do not need to call tzset() directly.

Other absolutes paths are still rejected.

Noted by pjanzen@ with input from deraadt@.

Reading time zone files from user-controlled paths can result in
pledge(2) or unveil(2) violations. We also ignore files that contain
a '.' character to avoid paths containing ".." or hidden files.

The tzcode package marked it dprecated in the late 1980ies
but it is universally supported and here to stay.
Triggered by a question from Rodrigo <hruodr at gmail dot com> on misc@.
William Ahern <william at 25thandclement dot com> listed a number of
sound arguments why it shouldn't be considered deprecated, in
particular that there is no better alternative, in particular none
that is thread-safe.
While here, fix the non-standard section name "NOTES", add the
missing STANDARDS section and provide additional information in the
HISTORY section, based on inspection of C89, C11, POSIX 2008, UNIX
v4 and v5 at TUHS, Tahoe and Reno at the CSRG archives, amd the
SunOS 3.5 and 4.0 manuals on bitsavers.
Reasearch on tzcode and SunOS history done by millert@.
OK millert@ on an earlier version of this patch,
and deraadt@ agrees with the general direction.

conversion specifications that are extensions; issues reported by
Andras Farkas <deepbluemistake at gmail dot com> on misc@.
While here, note that alternative conversion modifiers have no effect
and that flags and field width specifications are not supported.

value < 0. errno is only updated in this case. Change all (most?)
callers of syscalls to follow this better, and let's see if this strictness
helps us in the future.

i.e. those other than LC_CTYPE, into the CAVEATS section, and

They were originally defined in one way, then RFC822 erroneously
redefined them the opposite way, then RFC5322 said they can no
longer be used reliably.
So return NULL like FreeBSD, DragonFly, glibc, and musl do.
Issue reported by Hiltjo Posthuma <hiltjo at codemadness dot org>.
Deletion suggested by tedu@ and deraadt@.

Since strftime(3)'s %e conversion specification preceeds single digits by a
blank, do the converse here to allow safe data round trips through these
functions with the same format string.
Positive feedback tedu deraadt,

POSIX allows for one extra second in a minute, i.e. "23:59:60", so that leap
seconds can be parsed. They don't allow for *two* extra seconds, i.e.
"23:59:61", though.
Typo introduced in NetBSD lib/libc/time/strptime.c,v1.3.

Complete in the sense that all POSIX *locale(3) and *_l(3) functions
are included, but in OpenBSD, we of course only really care about
LC_CTYPE and we only support ASCII and UTF-8.
With important help from kettenis@, guenther@, and jca@.
Repeated testing in ports bulk builds by naddy@.
Additional testing by jca@, sebastia@, dcoppa@, and others.
OK kettenis@ dcoppa@, and guenther@ on an earlier version.

correctly - logically complete that now by removing MLINKS from base;
authors need only to ensure there is an entry in NAME for any function/
util being added. MLINKS will still work, and remain for perl to ease
upgrades;

applications like zdump(8) because pledge(2) doesn't allow access(2) to
/usr/share/zoneinfo.
millert@ better described why this call can go away:
"This looks like an attempt to do access checks based on the real uid instead
of the effective uid. Basically for setuid programs we don't want to allow a
user to set TZ to a path they should not be able to otherwise access.
However, we already have a check for issetugid() above so I think the doaccess
bits can just be removed and we can rely on open()."
After discussion with tb@, deraadt@ and millert@, this was also OK'ed by them
