Time appeared to skip a beat last week when some of the world’s most accurate clocks were affected by a wind-induced power ...

A collaboration between researchers in the US and Germany has made a major breakthrough in optical nuclear clocks, achieving laser-based excitation of Thoria-229 in a non-transparent host material.

Due to the power outage, time (very) briefly stood still at the NIST Internet Time Service facility in Boulder.

"As the typical uncertainty of time transfer over the public Internet is on the order of one millisecond (1/1000th of a ...

A destructive windstorm disrupted the power supply to more than a dozen atomic clocks that keep official time in the United ...

Officials said the error is likely too minute for the general public to clock it, but it could affect applications such as critical infrastructure, telecommunications and GPS signals.

The National Institute of Standards and Technology recently warned that an atomic clock device installed at its Boulder campus had failed due to a prolonged power ...

Scientists have taken another giant step towards building the most precise clock ever imagined—one that could display not only the passage of time, but shifting rules of nature itself. An ...

Nuclear clocks are the next big thing in ultra-precise timekeeping. Recent publications in the journal Nature propose a new method and new technology to build the clocks. Timekeeping has become more ...

The National Institute of Standards and Technology’s Internet Time Service Facility in Boulder lost power Wednesday afternoon ...

A severe windstorm in Colorado triggered a power failure at the National Institute of Standards and Technology (NIST), ...

Researchers are looking for new ways to improve timekeeping because even small gains in stability can help physicists discover subtle physical effects. The thorium-229 nuclear clock is a newer venture ...
