Does space have a standard time or do you rely on the time zones on Earth while you are in space?
Great question. Really it is up to the particular space agency/mission which time zone they use. For example, since the International Space Station is a collaboration between NASA, the Russian Space Agency, the European Space Agency, the Japanese Space Agency, and the Canadian Space Agency, we came up with the compromise of operating on Greenwich Mean Time (GMT). So, Space Station time is the same as London time! The International Space Station orbits our planet every 90 minutes, so of course we’re transiting across multiple time zones constantly.
