2022.6: Release of upstream tzdata 2022f

Version 2022.6

Upstream version 2022f released 2022-10-29T01:04:57+00:00

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.
