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

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

NIST traced the problem to its Boulder, Colorado campus, where a prolonged utility power outage disrupted operations. The ...

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

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 ...

Clocks on Earth are ticking a bit more regularly thanks to NIST-F4, a new atomic clock at the National Institute of Standards and Technology (NIST) campus in Boulder, Colorado. NIST-F4 measures an ...

Thanks to Einstein’s relativity, time flows differently on Mars than on Earth. NIST scientists have now nailed down the ...

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