Import tzdata2022f from
https://github.com/JodaOrg/global-tz/releases/download/2022fgtz/tzdata2022fgtz.tar.gz
Summary of changes in tzdata2022f (2022-10-28 18:04:57 -0700):
* Mexico will no longer observe DST after 2022, except for areas
near the US border that continue to observe US DST rules.
* Fiji will not observe DST in 2022/3.
* Simplify four Ontario zones, as most of the post-1970 differences
seem to have been imaginary.

News for the tz database
+Release 2022f - 2022-10-28 18:04:57 -0700
+
+ Briefly:
+ Mexico will no longer observe DST except near the US border.
+ Chihuahua moves to year-round -06 on 2022-10-30.
+ Fiji no longer observes DST.
+ Move links to 'backward'.
+ In vanguard form, GMT is now a Zone and Etc/GMT a link.
+ zic now supports links to links, and vanguard form uses this.
+ Simplify four Ontario zones.
+ Fix a Y2438 bug when reading TZif data.
+ Enable 64-bit time_t on 32-bit glibc platforms.
+ Omit large-file support when no longer needed.
+ In C code, use some C23 features if available.
+ Remove no-longer-needed workaround for Qt bug 53071.
+
+ Changes to future timestamps.
+
+ Mexico will no longer observe DST after 2022, except for areas
+ near the US border that continue to observe US DST rules.
+ On 2022-10-30 at 02:00 the Mexican state of Chihuahua moves
+ from -07 (-06 with DST) to year-round -06, thus not changing
+ its clocks that day. The new law states that Chihuahua
+ near the US border no longer observes US DST.
+
+ Fiji will not observe DST in 2022/3. (Thanks to Shalvin Narayan.)
+ For now, assume DST is suspended indefinitely.
+
+ Changes to data
+
+ Move links to 'backward' to ease and simplify link maintenance.
+ This affects generated data only if you use 'make BACKWARD='.
+
+ GMT is now a Zone and Etc/GMT a link instead of vice versa,
+ as GMT is needed for leap second support whereas Etc/GMT is not.
+ However, this change exposes a bug in TZUpdater 2.3.2 so it is
+ present only in vanguard form for now.
+
+ Vanguard form now uses links to links, as zic now supports this.
+
+ Changes to past timestamps
+
+ Simplify four Ontario zones, as most of the post-1970 differences
+ seem to have been imaginary. (Problem reported by Chris Walton.)
+ Move America/Nipigon, America/Rainy_River, and America/Thunder_Bay
+ to 'backzone'; backward-compatibility links still work, albeit
+ with some different timestamps before November 2005.
+
+ Changes to code
+
+ zic now supports links to links regardless of input line order.
+ For example, if Australia/Sydney is a Zone, the lines
+ Link Australia/Canberra Australia/ACT
+ Link Australia/Sydney Australia/Canberra
+ now work correctly, even though the shell commands
+ ln Australia/Canberra Australia/ACT
+ ln Australia/Sydney Australia/Canberra
+ would fail because the first command attempts to use a link
+ Australia/Canberra that does not exist until after the second
+ command is executed. Previously, zic had unspecified behavior if
+ a Link line's target was another link, and zic often misbehaved if
+ a Link line's target was a later Link line.
+
+ Fix line number in zic's diagnostic for a link to a link.
+
+ Fix a bug that caused localtime to mishandle timestamps starting
+ in the year 2438 when reading data generated by 'zic -b fat' when
+ distant-future DST transitions occur at times given in standard
+ time or in UT, not the usual case of local time. This occurs when
+ the corresponding .zi Rule lines specify DST transitions with TO
+ columns of 'max' and AT columns that end in 's' or 'u'. The
+ number 2438 comes from the 32-bit limit in the year 2038, plus the
+ 400-year Gregorian cycle. (Problem reported by Bradley White.)
+
+ On glibc 2.34 and later, which optionally supports 64-bit time_t
+ on platforms like x86 where time_t was traditionally 32 bits,
+ default time_t to 64 instead of 32 bits. This lets functions like
+ localtime support timestamps after the year 2038, and fixes
+ year-2038 problems in zic when accessing files dated after 2038.
+ To continue to limit time_t to 32 bits on these platforms, use
+ "make CFLAGS='-D_TIME_BITS=32'".
+
+ In C code, do not enable large-file support on platforms like AIX
+ and macOS that no longer need it now that tzcode does not use
+ off_t or related functions like 'stat'. Large-file support is
+ still enabled by default on GNU/Linux, as it is needed for 64-bit
+ time_t support.
+
+ In C code, prefer C23 keywords to pre-C23 macros for alignof,
+ bool, false, and true. Also, use the following C23 features if
+ available: __has_include, unreachable.
+
+ zic no longer works around Qt bug 53071, as the relevant Qt
+ releases have been out of support since 2019. This change affects
+ only fat TZif files, as thin files never had the workaround.
+
+ zdump no longer modifies the environ vector when compiled on
+ platforms lacking tm_zone or when compiled with -DUSE_LTZ=0.
+ This avoid undefined behavior on POSIX platforms.
+
+
