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… ...

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 ...

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), ...

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 ...

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).

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 ...

The BIPM in Sèvres near Paris routinely calculates the international time recommended for civil use (UTC, Coordinated Universal Time) from the comparison of atomic clocks via satellite ...

Time on the moon moves differently than it does on Earth, which means that using the terrestrial time system, called Coordinated Universal Time, or UTC, wouldn't work.

That's pretty much the same method used by humans to determine time on Earth (they call it Coordinated Universal Time, or UTC), and if it works here, it will work up there just as well.

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.

Most time zones down here on Earth are based on the universally recognized Coordinated Universal Time (UTC). A network of atomic clocks in different locations around the globe measures changes in ...
