Omsk Time

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.
