MOSCOW, October 25 (RIA Novosti) - Clocks across Russia will be set back an hour at 3:00 a.m. local time on Sunday morning, but there will be no change for astronauts on the ISS, Russian Mission Control said on Saturday.
The International Space Station (ISS) will continue to operate on Greenwich Mean Time, while Russian Mission Control will remain on Moscow Standard Time, which is three hours ahead of GMT and does not change for the summer.
Moscow Standard Time is used on all Russian piloted and unmanned spacecraft, and for ground-based tracking facilities.
Russia's Space Forces, responsible for the country's missile defenses, also operate on the fixed time.
The country's Defense Ministry also said that the switch over to winter time would not affect the preparedness of the country's armed forces.
