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.

Physicists uncover a universal limit on timekeeping precision, proving that anything from heartbeats to ocean waves can be a ...

Today’s most advanced clocks keep time with an incredibly precise rhythm. But a new experiment suggests that clocks’ precision comes at a price: entropy. Entropy, or disorder, is created each time a ...
