The NPL has developed a miniaturised Atomic Fountain Clock that promises to make accurate timekeeping technology smaller.

Due to the power outage, time (very) briefly stood still at the NIST Internet Time Service facility in Boulder.

Time signals shifted by a tiny amount that only very sensitive users would find upsetting UPDATED A staffer at the USA’s National Institute of Standards and Technology (NIST) tried to disable backup ...

A team of physicists has discovered a surprisingly simple way to build nuclear clocks using tiny amounts of rare thorium. By ...

How some of the world’s most precise clocks missed a very small beat. By Mike Ives and Adeel Hassan Time appeared to skip a beat last week when some of the world’s most accurate clocks were affected ...

The field of optical atomic clocks, in combination with ultracold atoms, has transformed precision timekeeping and metrology. By utilising laser-cooled atoms confined in optical lattices, researchers ...

NTP is one of the most interesting and important, but all to forgotten, protocols that makes the internet tick. Accurate ...

Atomic clocks and frequency standards represent the pinnacle of precision timekeeping technology. By harnessing the natural oscillatory behaviour of atoms, these devices deliver unparalleled accuracy ...

Atomic clocks record time using microwaves at a frequency matched to electron transitions in certain atoms. They are the basis upon which a second is defined. But there is a new kid on the block, the ...

Researchers at the ArQuS Laboratory of the University of Trieste (Italy) and the National Institute of Optics of the Italian National Research Council (CNR-INO) have achieved the first imaging of ...

NIST scientists have published results establishing a new atomic clock, NIST-F4, as one of the world’s most accurate timekeepers, priming the clock to be recognized as a primary frequency standard — ...
