+
+    Starting with release 2016b, some data entries cause zic implementations
+    derived from tz releases 2005j through 2015e to issue warnings like
+    "time zone abbreviation differs from POSIX standard (+03)".
+    These warnings should not otherwise affect zic's output and can safely be
+    ignored on today's platforms, as the warnings refer to a restriction in
+    POSIX.1-1988 that was removed in POSIX.1-2001.  One way to suppress the
+    warnings is to upgrade to zic derived from tz releases 2015f and later.

+# 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 Kzyl-Orda 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 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) [*]....

+# from 1992-03-27 No. 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.
+#
+# 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 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)....
+#
+# 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

+# 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 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

+# 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 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 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 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 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....[*]

+# 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.

+# From Paul Eggert (2016-04-15):
+# The tables below should reflect Stepan Golosunov's remarks above,
+# except for the items marked "[*]" which I haven't gotten to yet.
+# It looks like we will need new zones Asia/Atyrau and Asia/Qostanay
