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 powerful storm in Boulder, Colorado, caused a power outage that knocked the U.S. official atomic clock out of sync, ...

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 ...

A staffer at the USA’s National Institute of Standards and Technology (NIST) tried to disable backup generators powering some of its Network Time Protocol infrastructure, after a power outage around ...

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.

Now, physicists at the US National Institute of Standards and Technology (NIST) and the University of Delaware have developed the most accurate and precise atomic clock yet, using a 'web' of light to ...

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

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

Picture a clock ticking so steadily that it doesn’t lose a second, even after running for 1 billion years. Scientists are now closer than ever to realizing that level of timekeeping precision, new ...

The way time is measured is on the edge of a historic upgrade. At the heart of this change is a new kind of atomic clock that uses light instead of microwaves. This shift means timekeeping could ...

Considering that 90% of American adults own mobile phones, the practice of interrupting strangers to inquire about the time has almost completely disappeared. Since these devices are so prolific in ...

An extremely cold gas of strontium atoms is trapped in a web of light known as an optical lattice. The atoms are held in an ultrahigh-vacuum environment, which means there is almost no air or other ...
