What are you trying to achieve? How much accuracy do you need? To the second? Millisecond? Microsecond? What is your budget?
Receivers for the German DCF77 transmitter are very cheap (~20 EUR), but Moscow is near the limit of its range. See https://ru.wikipedia.org/wiki/DCF77 GPS has extremely accurate time (to nanosecond level internally), and works anywhere in the world. Cheap receivers don't synchronise the NMEA output to the time and can only be relied on to the nearest second. More carefully designed receivers can get you accuracy to somewhere between a microsecond and a millisecond. That's the best accuracy you can get without spending millions. If you have a good internet connection, then any reasonable PC (certainly Linux or MacOS) can calibrate its time to within a few milliseconds.
