Missions to the Moon currently communicate with team members on Earth using coordinated universal time (UTC) as a common temporal language. UTC’s timing is tied to an ensemble of atomic clocks.

NASA’s proposed LTC time zone is “a system that, while independent, maintains traceability to Earth’s Coordinated Universal Time (UTC) to facilitate seamless time conversion,” says Julian ...

While the space station doesn't have its own time zone, it runs on Coordinated Universal Time, or UTC, which is meticulously based on atomic clocks.

The shortest day recorded so far occurred July 5, 2024, when it came in 1.66 milliseconds short. The shortest day recorded ...

Leap seconds could become leap minutes, despite pushback from Russians, Vatican Already endangered, the leap second might have a practical successor soon.

Twenty-seven leap seconds have been added to Universal Coordinated Time since 1972. The addition of a leap second happens at the last tick of the clock on the night of Dec. 31 and June 30.

Precise Time Scale System, a world-class timing system that is traceable to Universal Coordinated Time (UTC) and not dependent on GNSS—providing nations, institutions, critical infrastructure ...

Because astronomers have divided the globe into 24 time zones, using one clock time worldwide is impractical. That’s why the times of astronomical events are often given in Universal Time (UT ...

Europe’s four Galileo satellites are now working as clocks accurate to a few billionths of a second, disseminating the exact time through their signals expressed as the UTC Universal Coordinated ...
