    Does Russia have more time zones than any other country?

    Yeah, Russia. "The sun never set on the British Empire" I think that goes to Russia (Sovyet Union?), as well. From Bering straight to Romania, I think there are more than 12 time zones. Especially if we follow geometry in the northern part of Russia/Sovyet Union
