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.

In the U.S., a new atomic clock called NIST-F4 has already proven to be one of the most precise timekeepers yet. ... Altogether, these clocks decide Coordinated Universal Time (UTC), ...

A new atomic clock is one of the world’s best timekeepers, researchers say — and after years of development, the “fountain”-style clock is now in use helping keep official U.S. time. Known ...

All the latest science news on coordinated universal time from Phys.org. Find the ... the moon's subtle gravitational pull has posed a vexing challenge—atomic clocks on its surface would tick ...

The world uses two primary systems for measuring time: GMT (and its various alternative names such as Zulu Time and Western European Time); and Coordinated Universal Time (UTC). The former is based on ...

All of the various clocks we use to track time, ... at the atomic clock timescale at the U.S. Naval ... a weighted average to determine the official Coordinated Universal Time (UTC).

Precision time is ubiquitous today thanks to GPS and WWVB. Even your Macbook or smartphone displays time which is synchronized to the NIST-F1 clock, a cesium fountain atomic clock (aka the ‘A… ...

Coordinated universal time (UTC) is an atomic time scale derived from a variation of the metallic element cesium's atom. This truly atomic "clock" ticks with microwave light about nine billion ...
