The new clock is so reliable that it would be off by less than a second if it had started running 100 million years ago, researchers say.

On a campus in Boulder, Colorado, time just became a little more exact. Inside the National Institute of Standards and Technology, or NIST, a new atomic clock named NIST-F4 has begun to tick ...

Every clock in your house probably tells a slightly different time. Now picture those clocks as the most precise instruments humanity has ever built, so accurate that they wouldn't lose or gain a ...

By comparing optical clocks in six different countries, researchers have taken a major step toward establishing a new global ...

We normally think of atomic clocks as the gold standard in timekeeping. The very definition of a second — in modern times, at least — is 9,192,631,770 periods of the radiation corresponding to ...

Atomic clocks in current GPS satellites will lose or gain a second on average every 3,000 years. ACES, on the other hand, “will not lose or gain a second in 300 million years,” says Luigi ...

At the heart of this change is a new kind of atomic clock that uses light instead of microwaves. This shift means timekeeping could become 1,000 times more accurate than today's standards.

The legal framework aims to ban unauthorized use of alternative time references, thereby establishing IST as the singular ...
