The National Institute of Standards and Technology (NIST) is changing the way it broadcasts time signals that synchronize radio-controlled "atomic" clocks and watches to official U.S. time in ways ...

Researchers at the National Institute of Standards and Technology (NIST) have used state-of-the-art atomic clocks, advanced light detectors, and a measurement tool called a frequency comb to boost the ...

Physicists have demonstrated the first next-generation 'time scale' -- a system that incorporates data from multiple atomic clocks to produce a single highly accurate timekeeping signal for ...

The National Institute of Standards and Technology building in Boulder, Colorado, houses lasers and quantum physics that unlock far more than the passage of time. NIST shares the building with the ...
