It is updated periodically to reflect changes made by political bodies to summer daylight saving time rules, UTC offsets, and time zone boundaries. The tzcode package provides the tzselect, zdump, and zic utilities. For more information, see the project home page: https://www.iana.org/time-zones For more details on changes, see the announcement or below: https://mm.icann.org/pipermail/tz-announce/2022-October/000075.html URGENT! Mexico is dropping DST *TONIGHT* with minimal notice, so this upgrade should be applied immediately if affected zones are important to your applications, or your clients. Other projects are unlikely to be able to update as quickly, so prepare to take mitigating actions on other platforms, or apply your own patches or updates. Some municipalities near the borders may or may not observe or drop DST depending on various factors, so more changes may be applied retroactively or with no notice in the coming days. Release 2022f 2022-10-28 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. * Simplify four Ontario zones. * Move links to 'backward'. * In vanguard form, GMT is now a Zone and Etc/GMT a link. 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. 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. 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.
