Stepan Golosunov (2016-03-27):

Review of the linked documents from http://adilet.zan.kz/
produced the following data for post-1991 Kazakhstan:

0. Act of the Cabinet of Ministers of the USSR
from 1991-02-04 No. 20
http://pravo.gov.ru/proxy/ips/?docbody=&nd=102010545
removed the extra hour ("decree time") on the territory of the USSR
starting with the last Sunday of March 1991.
It also allowed (but not mandated) Kazakh SSR, Kirghiz SSR, Tajik SSR,
Turkmen SSR and Uzbek SSR to not have "summer" time.

The 1992-01-13 act also refers to the act of the Cabinet of Ministers
of the Kazakh SSR from 1991-03-20 No. 170 "About the act of the Cabinet
of Ministers of the USSR from 1991-02-04 No. 20" but I didn't found its
text.

According to Izvestia newspaper No. 68 (23334) from 1991-03-20
-- page 6; available at http://libinfo.org/newsr/newsr2574.djvu via
http://libinfo.org/index.php?id=58564 -- on 1991-03-31 at 2:00 during
transition to "summer" time:
Republic of Georgia, Latvian SSR, Lithuanian SSR, SSR Moldova,
Estonian SSR; Komi ASSR; Kaliningrad oblast; Nenets autonomous okrug
were to move clocks 1 hour forward.
Kazakh SSR (excluding Uralsk oblast); Republic of Kyrgyzstan, Tajik
SSR; Andijan, Jizzakh, Namangan, Sirdarya, Tashkent, Fergana oblasts
of the Uzbek SSR were to move clocks 1 hour backwards.
Other territories were to not move clocks.
When the "summer" time would end on 1991-09-29, clocks were to be
moved 1 hour backwards on the territory of the USSR excluding
Kazakhstan, Kirghizia, Uzbekistan, Turkmenia, Tajikistan.

Apparently there were last minute changes. Apparently Kazakh act No. 170
was one of such changes.

https://ru.wikipedia.org/wiki/Декретное_время
claims that Sovetskaya Rossiya newspaper on 1991-03-29 published that
Nenets autonomous okrug, Komi and Kazakhstan (excluding Uralsk oblast)
were to not move clocks and Uralsk oblast was to move clocks
forward; on 1991-09-29 Kazakhstan was to move clocks backwards.
(Probably there were changes even after that publication. There is an
article claiming that Kaliningrad oblast decided on 1991-03-29 to not
move clocks.)

This implies that on 1991-03-31 Asia/Oral remained on +04/+05 while
the rest of Kazakhstan switched from +06/+07 to +05/06 or from +05/06
to +04/+05. It's unclear how Qyzylorda oblast moved into the fifth
time belt. (By switching from +04/+05 to +05/+06 on 1991-09-29?) ...

1. Act of the Cabinet of Ministers of the Republic of Kazakhstan
from 1992-01-13 No. 28
http://adilet.zan.kz/rus/docs/P920000028_
(text includes modification from the 1996 act)
introduced new rules for calculation of time, mirroring Russian
1992-01-08 act.  It specified that time would be calculated
according to time belts plus extra hour ("decree time"), moved clocks
on the whole territory of Kazakhstan 1 hour forward on 1992-01-19 at
2:00, specified DST rules.  It acknowledged that Kazakhstan was
located in the fourth and the fifth time belts and specified the
border between them to be located east of Qostanay and Aktyubinsk
oblasts (notably including Turgai and Qyzylorda oblasts into the fifth
time belt).

This means switch on 1992-01-19 at 2:00 from +04/+05 to +05/+06 for
Asia/Aqtau, Asia/Aqtobe, Asia/Oral, Atyraū and Qostanay oblasts; from
+05/+06 to +06/+07 for Asia/Almaty and Asia/Qyzylorda (and Arkalyk)....

2. Act of the Cabinet of Ministers of the Republic of Kazakhstan
from 1992-03-27 No. 284
http://adilet.zan.kz/rus/docs/P920000284_
cancels extra hour ("decree time") for Uralsk and Qyzylorda oblasts
since the last Sunday of March 1992, while keeping them in the fourth
and the fifth time belts respectively.

3. Order of the Prime Minister of the Republic of Kazakhstan
from 1994-09-23 No. 384
http://adilet.zan.kz/rus/docs/R940000384_
cancels the extra hour ("decree time") on the territory of Mangghystaū
oblast since the last Sunday of September 1994 (saying that time on
the territory would correspond to the third time belt as a
result)....

4. Act of the Government of the Republic of Kazakhstan
from 1996-05-08 No. 575
http://adilet.zan.kz/rus/docs/P960000575_
amends the 1992-01-13 act to end summer time in October instead
of September, mirroring identical Russian change from 1996-04-23 act.

5. Act of the Government of the Republic of Kazakhstan
from 1999-03-26 No. 305
http://adilet.zan.kz/rus/docs/P990000305_
cancels the extra hour ("decree time") for Atyraū oblast since the
last Sunday of March 1999 while retaining the oblast in the fourth
time belt.

This means change from +05/+06 to +04/+05....

6. Act of the Government of the Republic of Kazakhstan
from 2000-11-23 No. 1749
http://adilet.zan.kz/rus/archive/docs/P000001749_/23.11.2000
replaces the previous five documents.

The only changes I noticed are in definition of the border between the
fourth and the fifth time belts.  They account for changes in spelling
and administrative division (splitting of Turgai oblast in 1997
probably changed time in territories incorporated into Qostanay oblast
(including Arkalyk) from +06/+07 to +05/+06) and move Qyzylorda oblast
from being in the fifth time belt and not using decree time into the
fourth time belt (no change in practice).

7. Act of the Government of the Republic of Kazakhstan
from 2003-12-29 No. 1342
http://adilet.zan.kz/rus/docs/P030001342_
modified the 2000-11-23 act.  No relevant changes, apparently.

8. Act of the Government of the Republic of Kazakhstan
from 2004-07-20 No. 775
http://adilet.zan.kz/rus/archive/docs/P040000775_/20.07.2004
modified the 2000-11-23 act to move Qostanay and Qyzylorda oblasts into
the fifth time belt and add Aktobe oblast to the list of regions not
using extra hour ("decree time"), leaving Kazakhstan with only 2 time
zones (+04/+05 and +06/+07).  The changes were to be implemented
during DST transitions in 2004 and 2005 but the acts got radically
amended before implementation happened.

9. Act of the Government of the Republic of Kazakhstan
from 2004-09-15 No. 1059
http://adilet.zan.kz/rus/docs/P040001059_
modified the 2000-11-23 act to remove exceptions from the "decree time"
(leaving Kazakhstan in +05/+06 and +06/+07 zones), amended the
2004-07-20 act to implement changes for Atyraū, West Kazakhstan,
Qostanay, Qyzylorda and Mangghystaū oblasts by not moving clocks
during the 2004 transition to "winter" time.

This means transition from +04/+05 to +05/+06 for Atyraū oblast (no
zone currently), Asia/Oral, Asia/Aqtau and transition from +05/+06 to
+06/+07 for Qostanay oblast (Qostanay and Arkalyk, no zones currently)
and Asia/Qyzylorda on 2004-10-31 at 3:00....

10. Act of the Government of the Republic of Kazakhstan
from 2005-03-15 No. 231
http://adilet.zan.kz/rus/docs/P050000231_
removes DST provisions from the 2000-11-23 act, removes most of the
(already implemented) provisions from the 2004-07-20 and 2004-09-15
acts, comes into effect 10 days after official publication.
The only practical effect seems to be the abolition of the summer
time.

Unamended version of the act of the Government of the Russian Federation
No. 23 from 1992-01-08 [See 'europe' file for details].
Kazakh 1992-01-13 act appears to provide the same rules and 1992-03-27
act was to be enacted on the last Sunday of March 1992.

Stepan Golosunov (2016-11-08):

Turgai reorganization should affect only southern part of Qostanay
oblast.  Which should probably be separated into Asia/Arkalyk zone.
(There were also 1970, 1988 and 1990 Turgai oblast reorganizations
according to wikipedia.)

[For Qostanay] http://www.ng.kz/gazeta/195/hranit/
suggests that clocks were to be moved 40 minutes backwards on
1920-01-01 to the fourth time belt.  But I do not understand
how that could happen....

[For Atyrau and Oral] 1919 decree
(http://www.worldtimezone.com/dst_news/dst_news_russia-1919-02-08.html
and in Byalokoz) lists Ural river (plus 10 versts on its left bank) in
the third time belt (before 1930 this means +03).

The Korean Wikipedia entry gives the following sources for UT offsets:

1908: Official Journal Article No. 3994 (decree No. 5)
1912: Governor-General of Korea Official Gazette Issue No. 367
(Announcement No. 338)
1954: Presidential Decree No. 876 (1954-03-17)
1961: Law No. 676 (1961-08-07)

(Another source "1987: Law No. 3919 (1986-12-31)" was in the 2014-10-30
edition of the Korean Wikipedia entry.)

I guessed that time zone abbreviations through 1945 followed the same
rules as discussed under Taiwan, with nominal switches from JST to KST
when the respective cities were taken over by the Allies after WWII.

For Pyongyang, guess no changes from World War II until 2015, as we
have no information otherwise.

"SLST" seems to be reasonably recent and rarely used outside time
zone nerd sources.  I searched Google News and found three uses of
it in the International Business Times of India in February and
March of this year when discussing cricket match times, but nothing
since then (though there has been a lot of cricket) and nothing in
other English-language news sources.  Our old abbreviation "LKT" is
even worse.  For now, let's use a numeric abbreviation; we can
switch to "SLST" if it catches on.

a) Lithuanian SSR, Latvian SSR, Estonian SSR, Kaliningrad oblast:
second time belt rules without extra hour (Moscow-1);
b) Astrakhan, Kirov, Kuybyshev, Ulyanovsk oblasts: second time belt
rules (Moscow time)

11. Regions-violators, 1981-1982.
Wikipedia refers to
http://maps.monetonos.ru/maps/raznoe/Old_Maps/Old_Maps/Articles/022/3_1981.html
http://besp.narod.ru/nauka_1981_3.htm

The second link provides two articles scanned from the Nauka i Zhizn
magazine No. 3, 1981 and a scan of the short article attributed to
the Trud newspaper from February 1982.  The first link provides the
same Nauka i Zhizn articles converted to the text form (but misses
time belt changes map).

The second Nauka i Zhizn article says that in addition to
introduction of summer time on 1981-04-01 there are some time belt
border changes on 1981-10-01, mostly affecting Nenets Autonomous
Okrug, Krasnoyarsk Krai, Yakutia, Magadan Oblast and Chukotka
according to the provided map (colored one).  In addition to that
"time violators" (regions which were not using rules of the time
belts in which they were located) would not be moving off the DST on
1981-10-01 to restore the decree time usage.  (Komi ASSR was
supposed to repeat that move in October 1982 to account for the 2
hour difference.)  Map depicting "time violators" before 1981-10-01
is also provided.

The article from Trud says that 1981-10-01 changes caused problems
and some territories would be moved to pre-1981-10-01 time by not
moving to summer time on 1982-04-01.  Namely: Dagestan,
Kabardino-Balkar, Kalmyk, Komi, Mari, Mordovian, North Ossetian,
Tatar, Chechen-Ingush and Chuvash ASSR, Krasnodar and Stavropol
krais, Arkhangelsk, Vladimir, Vologda, Voronezh, Gorky, Ivanovo,
Kostroma, Lipetsk, Penza, Rostov, Ryazan, Tambov, Tyumen and
Yaroslavl oblasts, Nenets and Evenk autonomous okrugs, Khatangsky
district of Taymyr Autonomous Okrug.  As a result Evenk Autonomous
Okrug and Khatangsky district of Taymyr Autonomous Okrug would end
up on Moscow+4, Tyumen Oblast on Moscow+2 and the rest on Moscow
time.

http://astrozet.net/files/Zones/DOC/RU/1980-925.txt
attributes the 1982 changes to the Act of the Council of Ministers
of the USSR No. 126 from 18.02.1982.  1980-925.txt also adds
Udmurtia to the list of affected territories and lists Khatangsky
district separately from Taymyr Autonomous Okrug.  Probably erroneously.

The affected territories are currently listed under Europe/Moscow,
Asia/Yekaterinburg and Asia/Krasnoyarsk.

12. Udmurtia
The fact that Udmurtia is depicted as a violator in the Nauka i
Zhizn article hints at Izhevsk being on different time from
Kuybyshev before 1981-10-01. Udmurtia is not mentioned in the 1989 act.
http://astrozet.net/files/Zones/DOC/RU/1980-925.txt
implies Udmurtia was on Moscow time after 1982-04-01.
Wikipedia implies Udmurtia being on Moscow+1 until 1991.

...

All Russian zones are supposed to have by default a -1 change at
1991-03-31 2:00 (cancellation of the decree time in the USSR) and a +1
change at 1992-01-19 2:00 (restoration of the decree time in Russia).

There were some exceptions, though.
Wikipedia says newspapers listed Astrakhan, Saratov, Kirov, Volgograd,
Izhevsk, Grozny, Kazan and Samara as such exceptions for the 1992
change. (Different newspapers providing different lists. And some
lists found in the internet are quite wild.)

And apparently some exceptions were reverted in the last moment.
http://www.kaliningradka.ru/site_pc/cherez/index.php?ELEMENT_ID=40091
says that Kaliningrad decided not to be an exception 2 days before the
1991-03-31 switch and one person at
https://izhevsk.ru/forum_light_message/50/682597-m8369040.html
says he remembers that Samara opted out of the 1992-01-19 exception
2 days before the switch.

As this source says that historical time in the Canaries is obscure,
and it does not discuss Ceuta, stick with Shanks for now for that data.

In the 1918 and 1919 fallback transitions in Spain, the clock for
the hour-longer day officially kept going after midnight, so that
the repeated instances of that day's 00:00 hour were 24 hours apart,
with a fallback transition from the second occurrence of 00:59... to
the next day's 00:00.  Our data format cannot represent this
directly, and instead repeats the first hour of the next day, with a
fallback transition from the next day's 00:59... to 00:00.

Although the 1918 names were officially "United States Standard
Eastern Time" and similarly for "Central", "Mountain", "Pacific",
and "Alaska", in practice "Standard" was placed just before "Time",
as codified in 1966.  In practice, Alaska time was abbreviated "AST"
before 1968.  Summarizing the 1967 name changes:

In early February 1948, in response to California's electricity shortage,
PG&E changed power frequency from 60 to 59.5 Hz during daylight hours,
causing electric clocks to lose six minutes per day.  (This did not change
legal time, and is not part of the data here.)  See:
Ross SA. An energy crisis from the past: Northern California in 1948.
Working Paper No. 8, Institute of Governmental Studies, UC Berkeley,
1973-11.  https://escholarship.org/uc/item/8x22k30c

In another measure to save electricity, DST was instituted from 1948-03-14
at 02:01 to 1949-01-16 at 02:00, with the governor having the option to move
the fallback transition earlier.  See pages 3-4 of:
http://clerk.assembly.ca.gov/sites/clerk.assembly.ca.gov/files/archive/Statutes/1948/48Vol1_Chapters.pdf

In response:

Governor Warren received a torrent of objecting mail, and it is not too much
to speculate that the objections to Daylight Saving Time were one important
factor in the defeat of the Dewey-Warren Presidential ticket in California.
-- Ross, p 25

On December 8 the governor exercised the option, setting the date to January 1
(LA Times 1948-12-09).  The transition time was 02:00 (LA Times 1949-01-01).

Despite the controversy, in 1949 California voters approved Proposition 12,
which established DST from April's last Sunday at 01:00 until September's
last Sunday at 02:00. This was amended by 1962's Proposition 6, which changed
the fall-back date to October's last Sunday. See:

Unless otherwise specified, the source for data through 1990 is:
Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
San Diego: ACS Publications, Inc. (2003).
Unfortunately this book contains many errors and cites no sources.

Many years ago Gwillim Law wrote that a good source
for time zone data was the International Air Transport
Association's Standard Schedules Information Manual (IATA SSIM),
published semiannually.  Law sent in several helpful summaries
of the IATA's data after 1990.  Except where otherwise noted,
IATA SSIM is the source for entries after 1990.

For data circa 1899, a common source is:
Milne J. Civil time. Geogr J. 1899 Feb;13(2):173-94.
https://www.jstor.org/stable/1774359

These tables use numeric abbreviations like -03 and -0330 for
integer hour and minute UT offsets.  Although earlier editions used
alphabetic time zone abbreviations, these abbreviations were
invented and did not reflect common practice.

This says President Sixto Durán Ballén signed decree No. 285, which
established DST from 1992-11-28 to 1993-02-05; it does not give transition
times.  The people called it "hora de Sixto" ("Sixto hour").  The change did
not go over well; a popular song "Qué hora es" by Jaime Guevara had lyrics
that included "Amanecía en mitad de la noche, los guaguas iban a clase sin
sol" ("It was dawning in the middle of the night, the buses went to class
without sun").  Although Ballén's campaign slogan was "Ni un paso atrás"
(Not one step back), the clocks went back in 1993 and the experiment was not
repeated.  For now, assume transitions were at 00:00 local time country-wide.
