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 ...

Before January 2020, the two tied-for-lowest points for the Doomsday Clock were in 1953 (when the Clock was set to two minutes until midnight, after the U.S. and the Soviet Union began testing hydrogen bombs) and in 2018, following the failure of world leaders to address tensions relating to nuclear weapons and climate change issues. In other ...
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]
The Atomichron was the world's first commercial atomic clock, built by the National Company, Inc. of Malden, Massachusetts. It was also the first self-contained portable atomic clock and was a caesium standard clock. More than 50 clocks with the trademarked Atomichron name were produced. [1] [2] [3] [4]

UTC is calculated by the International Bureau of Weights and Measures (BIPM) [2] using weighted averages of the various times as reported by these 70+ listed timing centers. [ 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 ...
Of this amount, $7600 was spent on the eight round-the-world plane tickets, [13] including two seats on each flight for "Mr. Clock." They flew eastward around the world, ran the clocks side by side for a week, and then flew westward. The crew of each flight helped by supplying the navigational data needed for the comparison with theory.
