About Moscow time
Moscow runs on Moscow Standard Time, three hours ahead of UTC, the reference clock for European Russia and its railways.
Russia experimented with permanent DST, then permanent standard time, before fixing Moscow at UTC+3 in 2014. Uniquely, the entire Russian rail network historically ran on Moscow Time regardless of where a station actually was — spanning eleven zones — so travellers had to mentally convert local time at every stop. Moscow anchors that whole system.
