Physicists are getting closer to creating a long-sought ‘nuclear clock’. This device would keep time by measuring energy ...

This breakthrough in precision timing is about the size of your fingernail and only loses one second every 30,000 years.

China mass-produces fingernail-sized atomic clock with extreme precision, enabling advanced targeting, navigation and secure communications.

Scientists are exploring a new type of optical atomic clock based on ytterbium-173 ions that could help define the future standard for measuring time.

India's NavIC GPS alternative faces challenges after satellite IRNSS-1F failed, reducing operational satellites to three. A minimum of four is needed for complete coverage. The Union government last ...

AURORA, Colorado—Lockheed Martin and the U.S. Space Force are testing several new technologies aboard the next GPS III satellite, including a new digital atomic clock. Current GPS satellites carry a ...

In the realm of first-world problems, your cheap wall clock doesn’t keep time, so you have to keep setting it. The answer? Of course, you connect it to NTP and synchronize the clock with an atomic ...

To find out how clock accuracy is verified and which reference is used for comparison, we visited the Belarusian State Institute of Metrology (BelGIM), where most of the national standards are kept.

Time is almost up on the way we track each second of the day, with optical atomic clocks set to redefine the way the world measures one second in the near future. Researchers from Adelaide University ...
