I live in Omsk and we have both Moscow and Omsk time for reference. People don't usually say Omsk time time though, they just say our time (по нашему времени) or local time (по местному времени). Moscow time is also used as a standard time zone for trains, airports, international events etc. That's just for convenience though, to avoid confusion, it's much easier to keep track of one time zone than of a plethora of local time zones.
