For decades, atomic clocks have provided the most stable means of timekeeping. They measure time by oscillating in step with the resonant frequency of atoms, a method so accurate that it serves as the ...

A new comb-like computer chip could be the key to equipping drones, smartphones and autonomous vehicles with military-grade positioning technology that was previously confined to space agencies and ...

For Rooney, the history of timekeeping has many pivotal moments - but three he picks out when talking to DCD are the invention of the pendulum and the balance spring in the 1600s, and centuries later, ...

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 ...

Nuclear clocks are the next big thing in ultra-precise timekeeping. Recent publications in the journal Nature propose a new method and new technology to build the clocks. Timekeeping has become more ...

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.

As if timekeeping in the U.S. wasn’t already pretty accurate, the U.S. Department of Commerce’s National Institute of Standards and Technology (NIST) just declared a new atomic clock, the NIST-F2, to ...

This is the third time that the clock has been moved closer to midnight in the past five years. “Every second counts, and we are running out of time. It is a hard truth, but this is our reality,” ...
