International Atomic Time (abbreviated TAI, from its French name temps atomique international [1]) is a high-precision atomic coordinate time standard based on the notional passage of proper time on Earth's geoid. [2] TAI is a weighted average of the time kept by over 450 atomic clocks in over 80 national laboratories worldwide. [3]

NIST-F1 is a cesium fountain clock, a type of atomic clock, in the National Institute of Standards and Technology (NIST) in Boulder, Colorado, and serves as the United States' primary time and frequency standard. The clock took fewer than four years to test and build, and was developed by Steve Jefferts and Dawn Meekhof of the Time and ...
The Bulletin of the Atomic Scientists set the clock to 89 seconds before midnight - the theoretical point of annihilation. That is one second closer than it was set last year.
Leonard Rieser, chairman of the board of the Bulletin of the Atomic Scientists, moves the hand of the Doomsday Clock back to 17 minutes before midnight on Nov. 26, 1991.
The time on the symbolic clock was set at 90 seconds to midnight, the same as in 2023. Prior to that it had stood at 100 seconds to midnight, closer to destruction than at any point since it was ...
