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. + + Release 2022e - 2022-10-11 11:13:02 -0700 Briefly: diff --git a/contrib/tzdata/africa b/contrib/tzdata/africa index 7cbd6b0ecd73..92a61259f916 100644 --- a/contrib/tzdata/africa +++ b/contrib/tzdata/africa @@ -97,22 +97,6 @@ Zone Africa/Algiers 0:12:12 - LMT 1891 Mar 16 0:00 Algeria WE%sT 1981 May 1:00 - CET -# Angola -# Benin -# See Africa/Lagos. - -# Botswana -# See Africa/Maputo. - -# Burkina Faso -# See Africa/Abidjan. - -# Burundi -# See Africa/Maputo. - -# Cameroon -# See Africa/Lagos. - # Cape Verde / Cabo Verde # # From Paul Eggert (2018-02-16): @@ -127,9 +111,6 @@ Zone Atlantic/Cape_Verde -1:34:04 - LMT 1912 Jan 01 2:00u # Praia -2:00 - -02 1975 Nov 25 2:00 -1:00 - -01 -# Central African Republic -# See Africa/Lagos. - # Chad # Zone NAME STDOFF RULES FORMAT [UNTIL] Zone Africa/Ndjamena 1:00:12 - LMT 1912 # N'Djamena @@ -137,33 +118,29 @@ Zone Africa/Ndjamena 1:00:12 - LMT 1912 # N'Djamena 1:00 1:00 WAST 1980 Mar 8 1:00 - WAT -# Comoros -# See Africa/Nairobi. - -# Democratic Republic of the Congo -# See Africa/Lagos for the western part and Africa/Maputo for the eastern. +# Burkina Faso +# Côte d'Ivoire (Ivory Coast) +# The Gambia +# Ghana +# Guinea +# Iceland +# Mali +# Mauritania +# St Helena +# Senegal +# Sierra Leone +# Togo -# Republic of the Congo -# See Africa/Lagos. +# The other parts of the St Helena territory are similar: +# Tristan da Cunha: on GMT, say Whitman and the CIA +# Ascension: on GMT, say the USNO (1995-12-21) and the CIA +# Gough (scientific station since 1955; sealers wintered previously): +# on GMT, says the CIA +# Inaccessible, Nightingale: uninhabited -# Côte d'Ivoire / Ivory Coast # Zone NAME STDOFF RULES FORMAT [UNTIL] Zone Africa/Abidjan -0:16:08 - LMT 1912 0:00 - GMT -Link Africa/Abidjan Africa/Accra # Ghana -Link Africa/Abidjan Africa/Bamako # Mali -Link Africa/Abidjan Africa/Banjul # The Gambia -Link Africa/Abidjan Africa/Conakry # Guinea -Link Africa/Abidjan Africa/Dakar # Senegal -Link Africa/Abidjan Africa/Freetown # Sierra Leone -Link Africa/Abidjan Africa/Lome # Togo -Link Africa/Abidjan Africa/Nouakchott # Mauritania -Link Africa/Abidjan Africa/Ouagadougou # Burkina Faso -Link Africa/Abidjan Atlantic/Reykjavik # Iceland -Link Africa/Abidjan Atlantic/St_Helena # St Helena - -# Djibouti -# See Africa/Nairobi. ############################################################################### @@ -359,33 +336,6 @@ Rule Egypt 2014 only - Sep lastThu 24:00 0 - Zone Africa/Cairo 2:05:09 - LMT 1900 Oct 2:00 Egypt EE%sT -# Equatorial Guinea -# See Africa/Lagos. - -# Eritrea -# See Africa/Nairobi. - -# Eswatini (formerly Swaziland) -# See Africa/Johannesburg. - -# Ethiopia -# See Africa/Nairobi. -# -# Unfortunately tzdb records only Western clock time in use in Ethiopia, -# as the tzdb format is not up to properly recording a common Ethiopian -# timekeeping practice that is based on solar time.
