A new atomic clock is one of the world ... In an article in Metrologia evaluating the clock’s accuracy, researchers say the clock is accurate enough to help calibrate coordinated universal time (UTC).

The tick of the world clock depends on hundreds of atomic oscillators positioned ... agreed standard called Coordinated Universal Time, also known as UTC. UTC is defined by an agency of the ...

The time we now use around the world is called Universal time, or UT. It was formalized a century ago — here's how it works.

There are approximately 400 high-precision atomic clocks worldwide ... That is why atomic clocks form the backbone of Coordinated Universal Time (UTC) — which is used to set global time zones ...

They serve as "primary frequency standards" that work together to calibrate Coordinated Universal Time, or UTC (an agreed-upon system for keeping time using data from atomic clocks around the ...
