Most clocks, from wristwatches to the systems that run GPS and the internet, work by tracking regular, repeating motions. To build a clock, you need something that ticks in a perfectly repeatable way.

If time is money, then what is the value of a nanosecond (billionth of a second)? Well, if you are building a large network of distributed applications, it could mean a ten percent improvement in ...

You’d think that synchronizing the clocks across a fleet of modern servers is a solved problem, but it’s actually quite a hard challenge to solve, especially if you want to get to nanosecond accuracy.

Nuclear clocks are the next big thing in ultra-precise timekeeping. Recent publications in the journal Nature propose a new method and new technology to build the clocks. Timekeeping has become more ...
