The last time that digital clocks read 23:59:60 occurred on December 31, 2016. In an update from the International Earth ...

Time might be even stranger than Einstein imagined. Physicists are now exploring the possibility that a single clock could ...

Scientists propose a new atomic clock experiment that could reveal whether time itself follows the strange rules of quantum ...

In advance of hurricane force winds moving into Colorado earlier this week, Xcel Energy preemptively shut off power to protect areas of the state from extreme fire danger. But due to the outage, time ...

At this point, atomic clocks are old news. They’ve been quietly keeping our world on schedule for decades now, and have been through several iterations with each generation gaining more accuracy. They ...

To find out how clock accuracy is verified and which reference is used for comparison, we visited the Belarusian State Institute of Metrology (BelGIM), where most of the national standards are kept.

"This book provides a introduction to the physics of time and time measurement, from an historical perspective to the modern day. It discusses the stability and accuracy of atomic frequency standards, ...

For many years, cesium atomic clocks have been reliably keeping time around the world. But the future belongs to even more accurate clocks: optical atomic clocks. In a few years’ time, they could ...
