Import tzdata2022g from https://github.com/JodaOrg/global-tz/releases/download/2022ggtz/tzdata2022ggtz.tar.gz
Summary of changes in tzdata2022g (2022-11-29 08:58:31 -0800):
* In the Mexican state of Chihuahua, the border strip near the US
will change to agree with nearby US locations on 2022-11-30.
* Much of Greenland, represented by America/Nuuk, stops observing
winter time after March 2023, so its daylight saving time becomes
standard time.
* 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.
* 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.
* Singapore's 1981-12-31 change was at 16:00 UTC (23:30 local time),
not 24:00 local time.

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.)
+
+
