Does the UK have an atomic clock?
An atomic clock at the UK’s National Physical Laboratory (NPL) has the best long-term accuracy of any in the world, research has found. Studies of the clock’s performance, to be published in the journal Metrologia, show it is nearly twice as accurate as previously thought.
Will atomic clocks work outside US?
Do your clocks work outside of the US, like say in Europe? Unfortunately not. These clocks were designed only to pick up the US time signal therefore they only work in the US.
Where is atomic clock kept?
the U.S. Naval Observatory
The master atomic clock ensemble at the U.S. Naval Observatory in Washington, D.C., which provides the time standard for the U.S. Department of Defense.

Why is it called an atomic clock?
An atomic clock is the most accurate type of timepiece in the world, designed to measure time according to vibrations within atoms. The precision of an atomic clock, on the other hand, depends upon the fact that an atom, caused to oscillate, will always vibrate at the same frequency.
Who invented the atomic clock?

Atomic clock/Inventors
Most of the concepts that led to atomic clocks were developed by physicist Isidor Isaac Rabi and his colleagues at Columbia in the 1930s. Rabi in 1939 informally discussed with scientists at the National Bureau of Standards his idea of applying the team’s molecular beam magnetic resonance technique as a time standard.
What is atomic clock and how does it work?
In an atomic clock, the frequency of the quartz oscillator is transformed into a frequency that is applied to a collection of atoms. If the derived frequency is correct, it will cause many electrons in the atoms to change energy levels. If the frequency is incorrect, far fewer electrons will jump.
