24:00" for 2015-2019 and 2023 on. (Thanks to Steffen Thorsen.)
If I recall correctly, the trailing "s" was needed to work around
a Ramadan glitch that no longer seems to happen with the new rule,
so omit it in the new version.
When recently changing the 'Chile' ruleset in 'southamerica', I
forgot to update its copy 'ChileAQ' in 'antarctica'. This sort of
thing has been a continuing problem over the years. Attempt to
make further recurrences less likely by moving 'Antarctica/Palmer'
from 'antarctica' to 'southamerica', so that there's no need to
copy the rules in question.
* antarctica (ArgAQ, ChileAQ): Remove.

same executable as standard functions with standard time_t.
(tzset, tzsetwall) [time_tz]: Declare, so that the tz_-prefixed
version ins declared.

When using gawk and Posix TZ in tzselect, this warning is shown:
awk: cmd. line:1: warning: escape sequence `\.' treated as plain `.'
gawk treats '\.' as '.'
mawk treats '\.' as '\.'
both treat '\\.' as '\\.'
The 2nd and 3rd are corrrect for 'Mm.w.d'.
Test:
gawk 'BEGIN{ date = "\."; print date }'
gawk 'BEGIN{ date = "\\."; print date }'
versus:
mawk 'BEGIN{ date = "\."; print date }'
mawk 'BEGIN{ date = "\\."; print date }'
* tzselect.ksh (date): Fix bug that broke POSIX TZ checking with gawk.

Christos Zoulas reported a crash due to a tzsetlcl failure to
initialize data in some places, and requested that errno be set
when time functions fail; see:
http://mm.icann.org/pipermail/tz/2014-October/021754.html
While fixing this in a different way, I noticed and fixed another
instance of undefined behavior when read returns a too-small value.
* NEWS: Document this.
* localtime.c (union input_buffer): Rename from u_t.
(union input_buffer, union local_storage):
Move to top level so that two functions can use them.
(tzloadbody): New function, with most of the body of the old tzload.
Check for short reads that leave uninitialized buffers behind.
Define a new constant TZHEADSIZE for this, and use it to simplify
other code that already uses the concept.
(tzload): Use it. This removes the need for gotos. Return an errno
value; all callers changed.
(zoneinit): Return bool, not struct state *. Assume SP is nonnull.
All callers changed.
(zoneinit, tzalloc): Set errno on failure.
(tzsetlcl): Don't crash if zoneinit fails.
