Changes to future timestamps
Chile's 2022 DST start is delayed from September 4 to September 11.
(Thanks to Juan Correa.)
Iran plans to stop observing DST permanently, after it falls back
on 2022-09-21. (Thanks to Ali Mirjamali.)
Changes to past timestamps
Finish moving to 'backzone' the location-based zones whose
timestamps since 1970 are duplicates; adjust links accordingly.
This change ordinarily affects only pre-1970 timestamps, and with
the new PACKRATLIST option it does not affect any timestamps.
In this round the affected zones are Antarctica/Vostok,
Asia/Brunei, Asia/Kuala_Lumpur, Atlantic/Reykjavik,
Europe/Amsterdam, Europe/Copenhagen, Europe/Luxembourg,
Europe/Monaco, Europe/Oslo, Europe/Stockholm, Indian/Christmas,
Indian/Cocos, Indian/Kerguelen, Indian/Mahe, Indian/Reunion,
Pacific/Chuuk, Pacific/Funafuti, Pacific/Majuro, Pacific/Pohnpei,
Pacific/Wake and Pacific/Wallis, and the affected links are
Arctic/Longyearbyen, Atlantic/Jan_Mayen, Iceland, Pacific/Ponape,
Pacific/Truk, and Pacific/Yap.
From fall 1994 through fall 1995, Shanks wrote that Crimea's
DST transitions were at 02:00 standard time, not at 00:00.
(Thanks to Michael Deckers.)
Iran adopted standard time in 1935, not 1946. In 1977 it observed
DST from 03-21 23:00 to 10-20 24:00; its 1978 transitions were on
03-24 and 08-05, not 03-20 and 10-20; and its spring 1979
transition was on 05-27, not 03-21.
(Thanks to Roozbeh Pournader and Francis Santoni.)
Chile's observance of -04 from 1946-08-29 through 1947-03-31 was
considered DST, not standard time. Santiago and environs had moved
their clocks back to rejoin the rest of mainland Chile; put this
change at the end of 1946-08-28. (Thanks to Michael Deckers.)
Some old, small clock transitions have been removed, as people at
the time did not change their clocks. This affects Asia/Hong_Kong
in 1904, Asia/Ho_Chi_Minh in 1906, and Europe/Dublin in 1880.
Changes to zone name
Rename Europe/Kiev to Europe/Kyiv, as "Kyiv" is more common in
English now. Spelling of other names in Ukraine has not yet
demonstrably changed in common English practice so for now these
names retain old spellings, as in other countries (e.g.,
Europe/Prague not "Praha", and Europe/Sofia not "Sofiya").
