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

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

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.

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

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 ...

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

A collaboration between researchers in the US and Germany has made a major breakthrough in optical nuclear clocks, achieving ...

Nuclear clocks are a technology researchers have been working toward for decades. New research in theoretical physics brings them closer to reality.

The affected atomic clocks, mainly hydrogen masers and cesium beams, are essential for determining UTC(NIST), with 10 to 15 of them typically in active use at the Boulder laboratory.

For decades, atomic clocks have provided the most stable means of timekeeping. They measure time by oscillating in step with ...

A revolutionary achievement could pave the way for smaller, more efficient nuclear clocks. Last year, a research team led by UCLA achieved a milestone scientists had pursued for half a century. They s ...
