1564# The Government of Kazakhstan passed a resolution March 15 abolishing
1565# daylight saving time citing lack of economic benefits and health
1566# complications coupled with a decrease in productivity.
1567#
1568# From Branislav Kojic (in Astana) via Gwillim Law (2005-06-28):
1569# ... what happened was that the former Kazakhstan Eastern time zone
1570# was "blended" with the Central zone. Therefore, Kazakhstan now has
1571# two time zones, and difference between them is one hour. The zone
1572# closer to UTC is the former Western zone (probably still called the
1573# same), encompassing four provinces in the west: Aqtobe, Atyrau,
1574# Mangghystau, and West Kazakhstan. The other zone encompasses
1575# everything else.... I guess that would make Kazakhstan time zones
1576# de jure UTC+5 and UTC+6 respectively.

1591# From Stepan Golosunov (2016-03-27) ([*] means see later comments below):
1592# Review of the linked documents from http://adilet.zan.kz/
1593# produced the following data for post-1991 Kazakhstan:
1578#
1594#
1595# 0. Act of the Cabinet of Ministers of the USSR
1596# from 1991-02-04 No. 20
1597# http://pravo.gov.ru/proxy/ips/?docbody=&nd=102010545
1598# removed the extra hour ("decree time") on the territory of the USSR
1599# starting with the last Sunday of March 1991.
1600# It also allowed (but not mandated) Kazakh SSR, Kirghiz SSR, Tajik SSR,
1601# Turkmen SSR and Uzbek SSR to not have "summer" time.
1602#
1603# The 1992-01-13 act also refers to the act of the Cabinet of Ministers
1604# of the Kazakh SSR from 1991-03-20 No. 170 "About the act of the Cabinet
1605# of Ministers of the USSR from 1991-02-04 No. 20" but I didn't found its
1606# text.
1607#
1608# According to Izvestia newspaper No. 68 (23334) from 1991-03-20
1609# (page 6; available at http://libinfo.org/newsr/newsr2574.djvu via
1610# http://libinfo.org/index.php?id=58564) on 1991-03-31 at 2:00 during
1611# transition to "summer" time:
1612# Republic of Georgia, Latvian SSR, Lithuanian SSR, SSR Moldova,
1613# Estonian SSR; Komi ASSR; Kaliningrad oblast; Nenets autonomous okrug
1614# were to move clocks 1 hour forward.
1615# Kazakh SSR (excluding Uralsk oblast); Republic of Kyrgyzstan, Tajik
1616# SSR; Andijan, Jizzakh, Namangan, Sirdarya, Tashkent, Fergana oblasts
1617# of the Uzbek SSR were to move clocks 1 hour backwards.
1618# Other territories were to not move clocks.
1619# When the "summer" time would end on 1991-09-29, clocks were to be
1620# moved 1 hour backwards on the territory of the USSR excluding
1621# Kazakhstan, Kirghizia, Uzbekistan, Turkmenia, Tajikistan.
1622#
1623# Apparently there were last minute changes. Apparently Kazakh act No. 170
1624# was one of such changes.
1625#
1626# https://ru.wikipedia.org/wiki/������������������ ����������
1627# claims that Sovetskaya Rossiya newspaper on 1991-03-29 published that
1628# Nenets autonomous okrug, Komi and Kazakhstan (excluding Uralsk oblast)
1629# were to not move clocks and Uralsk oblast was to move clocks
1630# forward; on 1991-09-29 Kazakhstan was to move clocks backwards.
1631# (Probably there were changes even after that publication. There is an
1632# article claiming that Kaliningrad oblast decided on 1991-03-29 to not
1633# move clocks.)
1634#
1635# This implies that on 1991-03-31 Asia/Oral remained on +04/+05 while
1636# the rest of Kazakhstan switched from +06/+07 to +05/06 or from +05/06
1637# to +04/+05. It's unclear how Kzyl-Orda oblast moved into the fifth
1638# time belt. (By switching from +04/+05 to +05/+06 on 1991-09-29?) ...
1639#
1640# 1. Act of the Cabinet of Ministers of the Republic of Kazakhstan
1641# from 1992-01-13 No. 28
1642# http://adilet.zan.kz/rus/docs/P920000028_
1643# (text includes modification from the 1996 act)
1644# introduced new rules for calculation of time, mirroring Russian
1645# 1992-01-08 act. It specified that time would be calculated
1646# according to time belts plus extra hour ("decree time"), moved clocks
1647# on the whole territory of Kazakhstan 1 hour forward on 1992-01-19 at
1648# 2:00, specified DST rules. It acknowledged that Kazakhstan was
1649# located in the fourth and the fifth time belts and specified the
1650# border between them to be located east of Kustanay and Aktyubinsk
1651# oblasts (notably including Turgai and Kzyl-Orda oblasts into the fifth
1652# time belt).
1653#
1654# This means switch on 1992-01-19 at 2:00 from +04/+05 to +05/+06 for
1655# Asia/Aqtau, Asia/Aqtobe, Asia/Oral, Atyrau and Kustanay oblasts; from
1656# +05/+06 to +06/+07 for Asia/Almaty and Asia/Qyzylorda (and Arkalyk) [*]....
1657#
1658# 2. Act of the Cabinet of Ministers of the Republic of Kazakhstan
1659# from 1992-03-27 No. 284
1660# http://adilet.zan.kz/rus/docs/P920000284_
1661# cancels extra hour ("decree time") for Uralsk and Kzyl-Orda oblasts
1662# since the last Sunday of March 1992, while keeping them in the fourth
1663# and the fifth time belts respectively.
1664#
1665# 3. Order of the Prime Minister of the Republic of Kazakhstan
1666# from 1994-09-23 No. 384
1667# http://adilet.zan.kz/rus/docs/R940000384_
1668# cancels the extra hour ("decree time") on the territory of Mangystau
1669# oblast since the last Sunday of September 1994 (saying that time on
1670# the territory would correspond to the third time belt as a
1671# result)....
1672#
1673# 4. Act of the Government of the Republic of Kazakhstan
1674# from 1996-05-08 No. 575
1675# http://adilet.zan.kz/rus/docs/P960000575_
1676# amends the 1992-01-13 act to end summer time in October instead
1677# of September, mirroring identical Russian change from 1996-04-23 act.
1678#
1679# 5. Act of the Government of the Republic of Kazakhstan
1680# from 1999-03-26 No. 305
1681# http://adilet.zan.kz/rus/docs/P990000305_
1682# cancels the extra hour ("decree time") for Atyrau oblast since the
1683# last Sunday of March 1999 while retaining the oblast in the fourth
1684# time belt.
1685#
1686# This means change from +05/+06 to +04/+05.
1687#
1688# There is no zone for Atyrau currently (listed under Asia/Aqtau in
1689# zone1970.tab).[*]

1693# http://adilet.zan.kz/rus/archive/docs/P000001749_/23.11.2000
1694# replaces the previous five documents.
1695#
1696# The only changes I noticed are in definition of the border between the
1697# fourth and the fifth time belts. They account for changes in spelling
1698# and administrative division (splitting of Turgai oblast in 1997
1699# probably changed time in territories incorporated into Kostanay oblast
1700# (including Arkalyk) from +06/+07 to +05/+06) and move Kyzylorda oblast
1701# from being in the fifth time belt and not using decree time into the
1702# fourth time belt (no change in practice).[*]

1711# http://adilet.zan.kz/rus/archive/docs/P040000775_/20.07.2004
1712# modified the 2000-11-23 act to move Kostanay and Kyzylorda oblasts into
1713# the fifth time belt and add Aktobe oblast to the list of regions not
1714# using extra hour ("decree time"), leaving Kazakhstan with only 2 time
1715# zones (+04/+05 and +06/+07). The changes were to be implemented
1716# during DST transitions in 2004 and 2005 but the acts got radically
1717# amended before implementation happened.

1720# from 2004-09-15 No. 1059
1721# http://adilet.zan.kz/rus/docs/P040001059_
1722# modified the 2000-11-23 act to remove exceptions from the "decree time"
1723# (leaving Kazakhstan in +05/+06 and +06/+07 zones), amended the
1724# 2004-07-20 act to implement changes for Atyrau, West Kazakhstan,
1725# Kostanay, Kyzylorda and Mangystau oblasts by not moving clocks
1726# during the 2014 transition to "winter" time.
1727#
1728# This means transition from +04/+05 to +05/+06 for Atyrau oblast (no
1729# zone currently), Asia/Oral, Asia/Aqtau and transition from +05/+06 to
1730# +06/+07 for Kostanay oblast (Kostanay and Arkalyk, no zones currently)

2569# Time and no mention was made about the abbreviation.
2570#
2571# If we look at Sri Lanka Department of Government's "Official News
2572# Website of Sri Lanka" ... http://www.news.lk/ we can see that they
2573# use SLT as abbreviation in time stamp at the beginning of each news
2574# item....
2575#
2576# Within Sri Lanka I think LKT is well known among computer users and
2577# administrators. In my opinion SLT may not be a good choice because the
2578# nation's largest telcom / internet operator Sri Lanka Telcom is well
2579# known by that abbreviation - simply as SLT (there IP domains are
2580# slt.lk and sltnet.lk).
2581#
2582# But if indeed our government has adopted SLT as standard abbreviation
2583# (that we have not known so far) then it is better that it be used for
2584# all computers.
2770# From Paul Eggert (2016-10-18):
2771# "SLST" seems to be reasonably recent and rarely-used outside time
2772# zone nerd sources. I searched Google News and found three uses of
2773# it in the International Business Times of India in February and
2774# March of this year when discussing cricket match times, but nothing
2775# since then (though there has been a lot of cricket) and nothing in
2776# other English-language news sources. Our old abbreviation "LKT" is
2777# even worse. For now, let's use a numeric abbreviation; we can
2778# switch to "SLST" if it catches on.
2585
2779
2586# From Paul Eggert (2006-04-25):
2587# One possibility is that we wait for a bit for the dust to settle down
2588# and then see what people actually say in practice.
