Quantum clocks break energy limits, unlocking ultra-precise timekeeping with far-reaching tech, AI, and navigation impacts.

You want your child to unwind. You want to avoid a meltdown. But you also want them to get the sleep they need.

“The optical clock community is strongly motivated to obtain the best possible set of measurements before the SI second is ...

This paper proposes a TSNDO scheme utilizing time-sensitive networking to discipline clocks, providing precise time for distributed networks. The experimental results demonstrate that TSNDO achieves ...

He developed technologies that helped pave the way for the Global Positioning System and made foundational discoveries that ...

The U.S. military uses 24-hour military time to avoid confusion between a.m. and p.m. The Navy started using it in 1920, and ...

Are you ready for more sunlight in the evening? Daylight saving time starts at 2 a.m. on Sunday, March 9, 2025, meaning we will gain an hour of daylight in the evening but lose an hour of sleep ...

Researchers have shown, for the first time, that transmission of ultrastable optical signals from optical clocks across tens of kilometers of deployed multicore fiber is compatible with ...
