2023-01-19	Tests: Add missing library dependency for LibTimeZone tests	Sam Atkins

2022-10-18	LibTimeZone+LibJS: Update to TZDB version 2022e	Timothy Flynn
	https://mm.icann.org/pipermail/tz-announce/2022-October/000074.html This version changes America/Chicago's transtion from LMT to CST from 1883 Nov 18 12:09:24 to 1883 Nov 18 18:00.
2022-10-17	LibTimeZone: Default to UTC if parsing the TZ environment variable fails	Timothy Flynn
	Commit c3fd455 changed LibTimeZone to fall back to the system time zone when we fail to parse the TZ environment variable. This behavior differs from both our LibC and glibc; they abort parsing and default to UTC. This changes LibTimeZone to behave the same way to avoid a very awkward situation where some parts of the codebase thinks the timezone is UTC, and others think the timezone is whatever /etc/timezone indicates.
2022-09-28	LibTimeZone: Use the last DST rule in the TZDB if a match isn't found	Timothy Flynn
	Some time zones, like "Asia/Shanghai", use a set of DST rules that end before present day. In these cases, we should fall back to last possible RULE entry from the TZDB. The time zone compiler published by IANA (zic) performs the same fallback starting with version 2 of the time zone file format.
2022-08-25	LibTimeZone: Fix tests when ENABLE_TIME_ZONE_DATABASE_DOWNLOAD is OFF	Timothy Flynn

2022-01-31	Everywhere: Update copyrights with my new serenityos.org e-mail :^)	Timothy Flynn

2022-01-25	LibTimeZone: Handle time zones which begin the year in daylight savings	Timothy Flynn

2022-01-25	LibTimeZone: Add an API to retrieve both daylight and standard offsets	Timothy Flynn
	This API will also include the formatted name of the time zone, with respect for DST (e.g. EST vs EDT for America/New_York).
2022-01-23	LibJS+LibTimeZone+LibUnicode: Remove direct linkage to LibTimeZone	Timothy Flynn
	This is no longer needed now that LibTimeZone is included within LibC. Remove the direct linkage so that others do not mistakenly copy-paste the CMakeLists text elsewhere.
2022-01-19	LibJS+LibTimeZone+LibUnicode: Indicate whether a time zone is in DST	Timothy Flynn
	Return whether the time zone is in DST during the provided time from TimeZone::get_time_zone_offset,
2022-01-19	LibJS+LibTimeZone: Begin handling DST when computing time zone offsets	Timothy Flynn
	This also updates some expectations in a Temporal time zone offset test that is using a time stamp which is in DST for a few time zones.
2022-01-11	LibTimeZone: Operate in UTC-only mode when !ENABLE_TIME_ZONE_DATA	Linus Groh
	Instead of only having dummy functions that don't work with any input, let's at least support one time zone: 'UTC'. This matches the basic Temporal implementation for engines without ECMA-262, for example.
2022-01-11	LibTimeZone: Begin generating GMT offset rules for each time zone	Timothy Flynn
	This is a rather naive implementation, but serves as a first pass at determining the GMT offset for a time zone at a particular point in time. This implementation ignores DST (because we are not parsing any RULE entries yet), and ignores any offset patterns of the form "Mon>4" or "lastSun".
2022-01-11	LibTimeZone: Add methods to canonicalize a time zone name	Timothy Flynn

2022-01-11	LibTimeZone: Add method to convert a time zone to a string	Timothy Flynn

2022-01-11	LibTimeZone: Perform time-zone-from-string lookups case insensitively	Timothy Flynn
	Time zone names in the TZDB are defined to be case insensitive.
2022-01-11	LibTimeZone: Add a unit test for generated time zone data	Timothy Flynn
