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.

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

A power outage in Colorado slowed down the time set by atomic clocks at the NIST laboratory, which accounted for the official ...

Clocks on Mars tick faster by about 477 microseconds each Earth day, a new study suggests. This difference is significantly ...

A windstorm in Colorado caused a power outage at NIST, disrupting US official timekeeping and causing a 4.8-microsecond lag. Although atomic clocks ran on battery, a backup generator failure affected ...

A power outage at a key atomic clock facility led to the US official time slowing down by just under five millionths of a second last week, the country’s time watchdog said. A severe windstorm knocked ...
