Scientists anticipate that Earth's rotation will quicken enough to create three shorter days between July and August, ...

The tick of the world clock depends on hundreds of atomic oscillators positioned across the globe. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it ...

Yet, for the majority of atomic clocks, which are used to keep Universal Coordinated Time (UTC) from positions around the globe and make sure our cell phones, computers and GPS tech is ...

T iming from atomic clocks is now an integral part of data-center operations. The atomic clock time transmitted via Global Position System (GPS) and other Global Navigation Satellite System (GNSS) ...

Optical quantum clocks developed at the University of Adelaide have been proven to outperform GPS navigation systems by many ...

This reliable oscillation became the basis of the first atomic clocks developed in the 1940s and 1950s, and in 1967 the international organization that oversees standards for weights and measures ...

But the atomic era demanded more exact timekeeping, and the world began doing business by UTC in 1972. The two time scales, though, aren't quite in sync, because Earth spins a bit slower each year ...

On Earth, those zones are set using Coordinated Universal Time (UTC), which reflects a weighted average measurement of hundreds of extremely precise atomic clocks placed around the globe.

It's created using an ensemble of atomic clocks all over the globe: they feed their times into the Parisian central laboratory, thereby ensuring that every nation ticks in synchrony to within a ...

NIST scientists have published results establishing a new atomic clock, NIST-F4, as one of the world’s most accurate timekeepers, priming the clock to be recognized as a primary frequency ...

But for the most accurate atomic clock ever made, small changes in gravity matter a great deal. ... scientists can use them to provide that kind of resolution across the entire globe.
