The International Space Station (ISS) uses Coordinated Universal Time
(UTC), also known as Greenwich Mean Time (GMT), as its standard time.
UTC is the scientific standard of timekeeping for the world and is based
on atomic clocks.

The ISS is a partnership between five space agencies from 15 countries.
The station is continuously operated 24 hours a day, 7 days a week, 365
days a year. Crews from the U.S., Russia, Japan, Canada, and Europe live
and work on the ISS, which orbits Earth every 90 minutes.

 Of course UTC is used in manned space crafts and space vehicles
that need to communicate with the Earth.

Of course, "local time" invented by relativistic
idiots is practically useless (and so is wannabe
second defined by SI).
