What UTC and MSK Actually Are
UTC — Coordinated Universal Time
The global reference standard. Aviation, computing and science run on it. Standing at UTC as written, and the region does not change its clocks, so that offset holds all year.
UTC is not a place. It is a computed standard, kept within a second of mean solar time at Greenwich by atomic clocks, and it is the reference every other zone is defined against.
MSK — Moscow Time
Moscow, Saint Petersburg, Minsk. Standing at UTC+3:00 as written, and the region does not change its clocks, so that offset holds all year. Russia abolished daylight saving in 2014, so Moscow stays on UTC+3 all year.
Russia scrapped daylight saving in 2011 by staying permanently on summer time, found the dark winter mornings unpopular, and settled on permanent standard time in 2014.
What This Means in Practice
A gap you can rely on
Neither region changes its clocks, so this difference holds every day of the year. A recurring meeting booked once stays correct — worth knowing, because most cross-border pairs cannot say that.
