The Time from NPL is a radio signal broadcast from the Anthorn Radio Station near Anthorn, Cumbria, which serves as the United Kingdom's national time reference. [1] The time signal is derived from three atomic clocks installed at the transmitter site, and is based on time standards maintained by the UK's National Physical Laboratory (NPL) in Teddington. [2]
The United States Naval Observatory began the A.1 scale on 13 September 1956, using an Atomichron commercial atomic clock, followed by the NBS-A scale at the National Bureau of Standards, Boulder, Colorado on 9 October 1957. [9] The International Time Bureau (BIH) began a time scale, T m or AM, in July 1955, using both local caesium clocks and ...
Atomic clocks are installed at sites of time signal radio transmitters. [103] They are used at some long-wave and medium-wave broadcasting stations to deliver a very precise carrier frequency. [104] Atomic clocks are used in many scientific disciplines, such as for long-baseline interferometry in radio astronomy. [105]

[3] [4] BIPM lists the time differences between the UTC timing centers in a monthly publication called Circular T, which contains the most up to date list of contributors to UTC. [ 5 ] When available, links are provided to the relevant "Time Page" displaying the current time as shown from the given service.
On Tuesday, the clock was set at 89 seconds to midnight — the closest the world has ever been to that marker, according to the Bulletin of the Atomic Scientists, which established the clock in ...
The United Kingdom National Timing Centre is the proposed network of atomic clocks consisting of a central building, and a series of other locations across the UK. [1]The cost of the new system will cost £36 million, [2] but additionally the UK government has given £6.7 million through Innovate UK Funding and £40 million toward a new research program Quantum Technologies for fundamental ...
Humanity is closer to destroying itself, according to atomic scientists who revealed on Tuesday that the famous “Doomsday Clock” was set to 89 seconds to midnight — the closest it has ever been.
