Congratulations to the the team at the National Physical Laboratory – the United Kingdom officially has the most accurate clock… in the world!

If you were to leave the clock running for 138 million years, it would be out by just one single second. Running a caesium fountain to keep track of the time. With some nifty physics tracking the number of electromagnetic flips the caesium atoms make (which is an exact 9,192,631,770 times in a single perfect second).

With five our clocks in the world, and teams of physicists looking to get even more accuracy, we might not hold the record for long, but it’s a proud day for the NPL team.

More at NPL.
