This is the third time that the clock has been moved closer to midnight in the past five years. “Every second counts, and we ...

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 ...

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 ...
