Update time zone data files to tzdata release 2016d.

DST law changes in Russia (Magadan, Tomsk regions) and Venezuela.
Historical corrections for Russia.  There are new zone names Europe/Kirov
and Asia/Tomsk reflecting the fact that these regions now have different
time zone histories from adjacent regions.

# stayed in sync with Moscow after 1990, and that Aqtobe (formerly Aktyubinsk)
# and Aqtau (formerly Shevchenko) are the largest cities in their zones.
# Guess that Aqtau and Aqtobe diverged in 1995, since that's the first time

# From Paul Eggert (2006-03-22):
# German Iofis, ELSI, Almaty (2001-10-09) reports that Kazakhstan uses
# RussiaAsia rules, instead of switching at 00:00 as the IATA has it.

# Also go with the following claims of Shanks & Pottenger:

# 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) [*]....
#
# 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 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
# 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 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 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 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

# Kazakh 1992-01-13 act appears to provide the same rules and 1992-03-27

# from UTC+6 to UTC+7 and is supposed to come into effect on 2016-05-29 at
# 2:00. The bill needs to be approved in the second and the third readings by
