The IANA time zone database divides Mongolia into 2 zones. It needs more zones than there are clock settings because it also records history: two regions that keep the same time today get separate entries if their clocks differed at any point since 1970.
Ulan Bator lies at 106.9° east, where mean solar time is UTC+7:08 (four minutes per degree of longitude). The clocks run 52 min ahead of the sun, so on average the sun is highest at about 12:52 PM.
Daylight saving time in Mongolia
