News for the tz database
+Release 2022g - 2022-11-29 08:58:31 -0800
+
+ Briefly:
+ The northern edge of Chihuahua changes to US timekeeping.
+ Much of Greenland stops changing clocks after March 2023.
+ Fix some pre-1996 timestamps in northern Canada.
+ C89 is now deprecated; please use C99 or later.
+ Portability fixes for AIX, libintl, MS-Windows, musl, z/OS
+ In C code, use more C23 features if available.
+ C23 timegm now supported by default
+ Fixes for unlikely integer overflows
+
+ Changes to future timestamps
+
+ In the Mexican state of Chihuahua, the border strip near the US
+ will change to agree with nearby US locations on 2022-11-30.
+ The strip's western part, represented by Ciudad Juárez, switches
+ from -06 all year to -07/-06 with US DST rules, like El Paso, TX.
+ The eastern part, represented by Ojinaga, will observe US DST next
+ year, like Presidio, TX. (Thanks to Heitor David Pinto.)
+ A new Zone America/Ciudad_Juarez splits from America/Ojinaga.
+
+ Much of Greenland, represented by America/Nuuk, stops observing
+ winter time after March 2023, so its daylight saving time becomes
+ standard time. (Thanks to Jonas Nyrup and Jürgen Appel.)
+
+ Changes to past timestamps
+
+ Changes for pre-1996 northern Canada (thanks to Chris Walton):
+
+ Merge America/Iqaluit and America/Pangnirtung into the former,
+ with a backward compatibility link for the latter name.
+ There is no good evidence the two locations differ since 1970.
+ This change affects pre-1996 America/Pangnirtung timestamps.
+
+ Cambridge Bay, Inuvik, Iqaluit, Rankin Inlet, Resolute and
+ Yellowknife did not observe DST in 1965, and did observe DST
+ from 1972 through 1979.
+
+ Whitehorse moved from -09 to -08 on 1966-02-27, not 1967-05-28.
+
+ Colombia's 1993 fallback was 02-06 24:00, not 04-04 00:00.
+ (Thanks to Alois Treindl.)
+
+ Singapore's 1981-12-31 change was at 16:00 UTC (23:30 local time),
+ not 24:00 local time. (Thanks to Geoff Clare via Robert Elz.)
+
+ Changes to code
+
+ Although tzcode still works with C89, bugs found in recent routine
+ maintenance indicate that bitrot has set in and that in practice
+ C89 is no longer used to build tzcode. As it is a maintenance
+ burden, support for C89 is planned to be removed soon. Instead,
+ please use compilers compatible with C99, C11, C17, or C23.
+
+ timegm, which tzcode implemented in 1989, will finally be
+ standardized 34 years later as part of C23, so timegm is now
+ supported even if STD_INSPIRED is not defined.
+
+ Fix bug in zdump's tzalloc emulation on hosts that lack tm_zone.
+ (Problem reported by Đoàn Trần Công Danh.)
+
+ Fix bug in zic on hosts where malloc(0) yields NULL on success.
+ (Problem reported by Tim McBrayer for AIX 6.1.)
+
+ Fix zic configuration to avoid linkage failures on some platforms.
+ (Problems reported by Gilmore Davidson and Igor Ivanov.)
+
+ Work around MS-Windows nmake incompatibility with POSIX.
+ (Problem reported by Manuela Friedrich.)
+
+ Port mktime and strftime to debugging platforms where accessing
+ uninitialized data has undefined behavior (strftime problem
+ reported by Robert Elz).
+
+ Check more carefully for unlikely integer overflows, preferring
+ C23 <stdckdint.h> to overflow checking by hand, as the latter has
+ had obscure bugs.
+
+ Changes to build procedure
+
+ New Makefile rule check_mild that skips checking whether Link
+ lines are in the file 'backward'. (Inspired by a suggestion from
+ Stephen Colebourne.)
+

+# From Rives McDow (1999-11-08):
+# On October 31, when the rest of Nunavut went to Central time,
+# Pangnirtung wobbled. Here is the result of their wobble:
+#
+# The following businesses and organizations in Pangnirtung use Central Time:
+#
+# First Air, Power Corp, Nunavut Construction, Health Center, RCMP,
+# Eastern Arctic National Parks, A & D Specialist
+#
+# The following businesses and organizations in Pangnirtung use Eastern Time:
+#
+# Hamlet office, All other businesses, Both schools, Airport operator
+#
+# This has made for an interesting situation there, which warranted the news.
+# No one there that I spoke with seems concerned, or has plans to
+# change the local methods of keeping time, as it evidently does not
+# really interfere with any activities or make things difficult locally.
+# They plan to celebrate New Year's turn-over twice, one hour apart,
+# so it appears that the situation will last at least that long.
+# The Nunavut Intergovernmental Affairs hopes that they will "come to
+# their senses", but the locals evidently don't see any problem with
+# the current state of affairs.
+
+# From Michaela Rodrigue, writing in the
+# Nunatsiaq News (1999-11-19):
+# http://www.nunatsiaqonline.ca/archives/nunavut991130/nvt91119_17.html
+# Clyde River, Pangnirtung and Sanikiluaq now operate with two time zones,
+# central - or Nunavut time - for government offices, and eastern time
+# for municipal offices and schools.... Igloolik [was similar but then]
+# made the switch to central time on Saturday, Nov. 6.
+
+# From Chris Walton (2022-11-06):
+# The implication is that Pangnirtung and Qikiqtarjuaq have observed Eastern
+# Time as far back as 1984 (and likely even further back than that).
+# It is possible that these communities never actually observed Atlantic
+# Time, but that would be difficult to prove.
+# From Paul Eggert (2022-11-06):
+# This is in 'backzone' as we have no good evidence that Pangnirtung differs
+# from America/Iqaluit since 1970. A Google Books snippet view of
+# volume 2, page 186 of "Pilot of Arctic Canada", published 1959 by
