Good luck with the metro clock. I once saw the difference in time between the stations at 10 minutes, when the train was driving a minute and a half from the force :) Once you have an injection - the time services are not easier to check? and :)
It is...
Moscow stations are the gates of the city.Concessionaries hardly broke into the exit and found themselves on the Kalanchev Square.Right of them, the heraldic chickens of Yaroslavl station rose.Directly against them, the October station blinked, painted with oil paint in two colors. The clock showed five minutes on eleven. At the time of Yaroslavsky it was exactly ten. And looking at the dark-blue, decorated with the signs of the Zodiac plate of the Ryazan station, travelers noticed that the clock showed without five and ten.
Very convenient for a date!
