You can generate a table of sunrises and sunsets from the US Naval Observatory, http://aa.usno.navy.mil/data/docs/RS_OneYear.php . Unfortunately I don't see a way to link directly to the table; Moscow is 55 45 N, 37 36 E, and now four hours east of Greenwich. From their location, they're "naturally" around UTC+2:30 (37.6 degrees, divided by 15 degrees per hour).

The table says that in late December the sun will rise at around 10 AM and set at around 5 PM. This doesn't seem preferable to the 9-4 they'd have under standard time. I'm not sure about Russian time zone boundaries, though; is Moscow time used in areas to the east of Moscow?

Moscow time is used in the North-West region, there are 9 time zones in total: http://en.wikipedia.org/wiki/File:Map_of_Russia_-_Time_Zones...
