In this work, a rubidium fountain clock through an 84km commercial optical fiber link was used to steer the atomic time scale generated by a clock ensemble with 2 hydrogen masers and 8 high ...

July 9 was unusually short thanks to changes in how fast the Earth is spinning. But two other days this summer are expected to be even shorter.

Earth’s rotation has been accelerating, and this week’s date is among several projected to be fractions of a millisecond shorter than usual.

Due to the way Earth's rotation is measured, Wednesday, July 9 will technically lose time. Here's why you most likely won't notice.

SummaryWe present a compact device which is capable to automatically and in real-time controls the magnetic field in an optical atomic clock. The device is controlled via TTL signals and is programmed ...

The U.N. nuclear watchdog, which polices the global nuclear Non-Proliferation Treaty, has not been able to carry out inspections in Iran since Israel launched military strikes on its nuclear ...

A festinating new theory shifts focus from space to time, arguing the clock-ticking we take for granted is richer and weirder than imagined.
