Earth’s quicker spin challenges civil time as experts weigh a first negative leap second to keep satellites, networks, and ...

The way time is measured is on the edge of a historic upgrade. At the heart of this change is a new kind of atomic clock that uses light instead of microwaves. This shift means timekeeping could ...

Every time you check the time on your phone, make an online transaction, or use a navigation app, you are depending on the precision of atomic clocks. Scientists are developing next-generation atomic ...

NIST scientists have published results establishing a new atomic clock, NIST-F4, as one of the world’s most accurate timekeepers, priming the clock to be recognized as a primary frequency standard — ...

STATEN ISLAND, N.Y. — When Daylight Saving Time arrives next month, we have to set our clocks ahead one hour. But do we, really? Many of the clocks we rely on daily actually do the resetting all by ...

Atomic clocks record time using microwaves at a frequency matched to electron transitions in certain atoms. They are the basis upon which a second is defined. But there is a new kid on the block, the ...

Scientists learned that reading a quantum clock requires orders of magnitude more energy than running it. This surprising imbalance reveals that observation itself shapes the flow and thermodynamics ...

There are significantly different architectures for what are known as “atomic” clocks. Optically driven atomic clocks offer a new set of performance attributes. The optical atomic clocks use paired ...

On Sunday, Nov. 2, we head back into Standard Time and say goodbye to Daylight Saving Time until March 8, 2026.
