Omsk used to have its own time zone- MSK+3,
Novosibirsk, Kemerovo and Krasnoyarsk used time zone- MSK+4 ...

In 1993- Novosibirsk moved to Omsk time zone:
Omsk and Novosibirsk- MSK+3 (UTC+6) , Kemerovo stay in Krasnoyarsk time zone- 
MSK+4 (UTC+7).

In 2010- Kemerovo also moved to Omsk and Novosibirsk time zone- MSK+3(UTC+6).

Right now all 3 cities:  Omsk, Novosibirsk, Kemerovo use the same time zone 
MSK+3 (UTC+6) (which could as listed as Omsk time zone, or Novosibirsk time 
Krasnoyarsk use time zone MSK+4 (UTC+7).

Time zones in Russia are in transition (revision) as of now- It won't be 
surprise that additional changes for many time zones in Russia will happened 
this fall (during transition from Summer time to Standard time). 

Current new Russia map (Kemerovo in the same time zone as Omsk, Novosibirsk- 
green color):
