It is updated periodically to reflect changes made by political bodies to daylight saving (summer time) rules, UTC offsets, and time zone boundaries. The tzcode package provides the tzselect, zdump, and zic utilities. For more details on changes, please see the announcement or below: https://mm.icann.org/pipermail/tz-announce/2022-March/000070.html Release 2022a - 2022-03-15 23:02:01 -0700 Briefly: * Palestine will spring forward on 2022-03-27, not -03-26. * zdump -v now outputs better failure indications. * Bug fixes for code that reads corrupted TZif data. Changes to future timestamps * Palestine will spring forward on 2022-03-27, not 2022-03-26. Predict future transitions for first Sunday >= March 25. Additionally, predict fallbacks to be the first Friday on or after October 23, not October's last Friday, to be more consistent with recent practice. The first differing fallback prediction is on 2025-10-24, not 2025-10-31. Changes to past timestamps * From 1992 through spring 1996, Ukraine's DST transitions were at 02:00 standard time, not at 01:00 UTC. * Chile's Santiago Mean Time and its LMT precursor have been adjusted eastward by 1 second to align with past and present law. Changes to commentary * Add several references for Chile's 1946/1947 transitions, some of which only affected portions of the country. Changes to code * Fix bug when mktime gets confused by truncated TZif files with unspecified local time. * Fix bug when 32-bit time_t code reads malformed 64-bit TZif data. * When reading a version 2 or later TZif file, the TZif reader now validates the version 1 header and data block only enough to skip over them, as recommended by RFC 8536 section 4. Also, the TZif reader no longer mistakenly attempts to parse a version 1 TZIf file header as a TZ string. * zdump -v now outputs "(localtime failed)" and "(gmtime failed)" when local time and UT cannot be determined for a timestamp. Changes to build procedure * Distribution tarballs now use standard POSIX.1-1988 ustar format instead of GNU format. Although the formats are almost identical for these tarballs, ustar headers' magic fields contain "ustar" instead of "ustar ", and their version fields contain "00" instead of " ". The two formats are planned to diverge more significantly for tzdb releases after 2242-03-16 12:56:31 UTC, when the ustar format becomes obsolete and the tarballs switch to pax format, an extension of ustar. For details about these formats, please see "pax - portable archive interchange", IEEE Std 1003.1-2017, .
