MSK is the abbreviation for Moscow Standard Time, a time zone offset of UTC+3. It applies in
Western Russia.
Russia abolished daylight saving in 2011, so Moscow stays on UTC+3 all year.
Time-zone abbreviations are convenient but not unique or official — several codes are shared by
more than one zone. When precision matters, use the underlying IANA zone name (for example
Europe/Moscow) or the UTC offset UTC+3 instead.
