They go by Greenwich Mean Time. By convention, the ISS astronauts set their clocks to ring in the New Year with those in London, Reykjavik, and Accra. The crew of the space station may also exchange holiday greetings with mission controllers in Moscow and Houston at the local midnights in those two places—9 p.m. and 6 a.m. GMT, respectively. Though Sinapore isn’t too bad either.
