A clock built by a team led by researchers at the National Institute of Standards and Technology (NIST) has been estimated to be 41 percent more accurate than the previous timekeeping record holder.

Atomic clocks have long been the gold standard for measuring time and frequency. Among them, optical clocks—using atoms like strontium or aluminum—have reached staggering levels of accuracy, with ...

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 ...

In the Aug. 30 issue of The Loop newspaper I wrote about super accurate atomic clocks for space travel and said to think of ...

(Bloomberg) — If time is money, precision in nanoseconds can be measured in millions of dollars. Shimadzu Corp, a Kyoto, Japan-based precision equipment maker, has started selling a clock which is ...

In the early 19th century, as the sun moved across Britain from east to west, people set their clocks to local mean time, so that noon in Greenwich would occur about 16½ minutes before noon in ...

DENVER (KDVR) — It is said that time is relative and passes differently depending on an observer’s relative motion and gravitational potential. Although some would argue time is a construct, it does ...
