History
editUntil 1991, Omsk Time was one of the two time zones used in Soviet Central Asia. In addition to Omsk Oblast in the Russian SFSR, it covered the eastern two thirds of Kazakh SSR, all of Kyrgyz and Tajik SSRs, and eastern Uzbek SSR. This included the city of Omsk and the capitals Alma-Ata (Almaty), Frunze (Bishkek), Dushanbe and Tashkent.
For two years after the collapse of the Soviet Union, Omsk Oblast remained the only region in Russia in this time zone. The newly independent Central Asian states ceased to observe daylight saving time, while Uzbekistan and Tajikistan in addition "moved west" by adjusting the clocks one hour back.
From the 1990s to the 2010s, Russia experienced a countrywide wave of clock shifts towards Moscow. By 2010, all Western Siberia's Moscow 4 regions moved to Moscow 3, merging into Omsk Time.
In 2011, Russia moved to year-round daylight saving time. Instead of switching between UTC 06:00 in winter and UTC 07:00 in summer, Omsk time was set to UTC 07:00 until 2014, when it was reset back to UTC 06:00 year-round, but Kemerovo Oblast decided to stay in UTC 07:00 - Krasnoyarsk Time.
In 2016, Altai Krai, Altai Republic,[2] Tomsk Oblast,[3] and Novosibirsk Oblast[4] switched to Krasnoyarsk Time (UTC 07:00).
Omsk Oblast is now the only part of Russia which uses this time zone.
