Hi!

While searching for the text of the 1988 act "about a change in
calculation of time on the territories of Volgograd and Saratov
oblasts" I ran into a similarly titled document from 1992
Kazakhstan.  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 04.02.1991 N 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 13.01.1992 act also refers to the act of the Cabinet of Ministers
of the Kazakh SSR from 20.03.1991 N 170 "About the act of the Cabinet
of Ministers of the USSR from 04.02.1991 N 20" but I didn't found its
text.

According to Izvestia newspaper № 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 N 170
was one of such changes.

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 Kzyl-Orda oblast moved into the fifth
time belt. (By switching from +04/+05 to +05/+06 on 1991-09-29?)

Currently tzdata says that all Kazakh zones remained on +04, +05 or
+06 during the whole 1991 year. This is inconsistent (except for
Asia/Qyzylorda) with the 1992 documents.


1. Act of the Cabinet of Ministers of the Republic of Kazakhstan
from 13.01.1992 N 28
http://adilet.zan.kz/rus/docs/P920000028_
(text includes modification from the 1996 act)
introduced new rules for calculation of time, mirroring Russian
08.01.1992 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 Kustanay and Aktyubinsk
oblasts (notably including Turgai and Kzyl-Orda 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, Atyrau and Kustanay oblasts; from
+05/+06 to +06/+07 for Asia/Almaty and Asia/Qyzylorda (and Arkalyk).

Currently tzdata contains only Asia/Qyzylorda change.


2. Act of the Cabinet of Ministers of the Republic of Kazakhstan
from 27.03.1992 N 284
http://adilet.zan.kz/rus/docs/P920000284_
cancels extra hour ("decree time") for Uralsk and Kzyl-Orda oblasts
since the last Sunday of March 1992, while keeping them in the fourth
and the fifth time belts respectively.

This means change from +05/+06 to +04/+05 for Asia/Oral and from
+06/+07 to +05/+06 for Asia/Qyzylorda on 1992-03-29.


3. Order of the Prime Minister of the Republic of Kazakhstan
from 23.09.1994 N 384
http://adilet.zan.kz/rus/docs/R940000384_
cancels the extra hour ("decree time") on the territory of Mangystau
oblast since the last Sunday of September 1994 (saying that time on
the territory would correspond to the third time belt as a
result).

This means change from +05/+06 to +04/+05 for Asia/Aqtau.

Current tzdata guesses the change was done in 1995:

# Guess that Aqtau and Aqtobe diverged in 1995, since that's the first time
# IATA SSIM mentions a third time zone in Kazakhstan.

			5:00 RussiaAsia	AQT%sT	1995 Mar lastSun  2:00 # Aqtau Time
			4:00 RussiaAsia	AQT%sT	2005 Mar 15


4. Act of the Government of the Republic of Kazakhstan
from 08.05.1996 N 575
http://adilet.zan.kz/rus/docs/P960000575_
amends the 13.01.1992 act to end summer time in October instead
of September, mirroring identical Russian change from 23.04.1996 act.


5. Act of the Government of the Republic of Kazakhstan
from 26.03.1999 N 305
http://adilet.zan.kz/rus/docs/P990000305_
cancels the extra hour ("decree time") for Atyrau 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.

There is no zone for Atyrau currently (listed under Asia/Aqtau in
zone1970.tab).


6. Act of the Government of the Republic of Kazakhstan
from 23.11.2000 N 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 Kostanay oblast
(including Arkalyk) from +06/+07 to +05/+06) and move Kyzylorda 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 29.12.2003 N 1342
http://adilet.zan.kz/rus/docs/P030001342_
modified the 23.11.2000 act.  No relevant changes, apparently.


8. Act of the Government of the Republic of Kazakhstan
from 20.07.2004 N 775
http://adilet.zan.kz/rus/archive/docs/P040000775_/20.07.2004
modified the 23.11.2000 act to move Kostanay and Kyzylorda 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 15.09.2004 N 1059
http://adilet.zan.kz/rus/docs/P040001059_
modified the 23.11.2000 act to remove exceptions from the "decree time"
(leaving Kazakhstan in +05/+06 and +06/+07 zones), amended the
20.07.2004 act to implement changes for Atyrau, West Kazakhstan,
Kostanay, Kyzylorda and Mangystau oblasts by not moving clocks
during the 2014 transition to "winter" time.

This means transition from +04/+05 to +05/+06 for Atyrau oblast (no
zone currently), Asia/Oral, Asia/Aqtau and transition from +05/+06 to
+06/+07 for Kostanay oblast (Kostanay and Arkalyk, no zones currently)
and Asia/Qyzylorda on 2004-10-31 at 3:00.  Currently tzdata has some
of these transitions on 2015-03-15.


10. Act of the Government of the Republic of Kazakhstan
from 15.03.2005 N 231
http://adilet.zan.kz/rus/docs/P050000231_
removes DST provisions from the 23.11.2000 act, removes most of the
(already implemented) provisions from the 20.07.2004 and 15.09.2004
acts, comes into effect 10 days after official publication.
The only practical effect seems to be the abolition of the summer
time.

Current tzdata says the change was on 2005-03-15 but the act was not
supposed to come into effect until at least 10 days later. It would be
simpler to use the 2004-10-31 date.





Unamended version of the
act of the Government of the Russian Federation
N 23 from 08.01.1992
http://pravo.gov.ru/proxy/ips/?docbody=&nd=102014034&rdk=0
says that every year clocks were to be moved forward on last Sunday of
March at 2 hours and moved backwards on last Sunday of September at 3
hours.  It was amended in 1996 to replace September with October.
Kazakh 13.01.1992 act appears to provide the same rules and 27.03.1992
act was to be enacted on the last Sunday of March 1992.

Is there any reason why tzdata contains exception for 1992?

Rule	Russia	1992	only	-	Mar	lastSat	 23:00	1:00	S
Rule	Russia	1992	only	-	Sep	lastSat	 23:00	0	-

Rule RussiaAsia	1992	only	-	Mar	lastSat	23:00	1:00	S
Rule RussiaAsia	1992	only	-	Sep	lastSat	23:00	0	-

(Hmm. Was the source for the 1992 transitions providing data for
Moscow in UTC?)
