Sonic Youth Gossip - New date for Doomsday due to be set today at 2.30pm (GMT)

The Doomsday Clock is a symbolic clockface maintained since 1947 by the Board of Directors of the Bulletin of the Atomic Scientists at the University of Chicago. It uses the analogy of the human race being at a time that is "minutes to midnight" where midnight represents destruction by nuclear war. The clock has appeared on the cover of each issue of the Bulletin of the Atomic Scientists since its introduction. The clock is currently set to six minutes to midnight, most recently updated on January 17, 2007.

The Doomsday Clock was started at seven minutes to midnight during the Cold War in 1947, and has subsequently been moved forwards or backwards at intervals, depending on the state of the world and the prospects for nuclear war. Its setting is relatively arbitrary, set by the Board of Directors at the Bulletin of the Atomic Scientists in response to global affairs. The setting of the clock has not always been fast enough to cope with the speed of global events, either; one of the closest periods to nuclear war, the Cuban Missile Crisis in 1962, reached its head and resolution in a number of weeks, and the clock either could not be changed or was not changed to reflect any of this at the time. Nevertheless, the changing of the clock usually does provoke attention.

It was announced on 13 January, 2007 that the clock would move forward on 17 January, 2007 to reflect what the Board of Directors call worsening nuclear and climate threats to the world. Before this, the clock was changed in 2002 back to seven minutes to midnight, after recent deterioration in international relations. Each time nuclear conflict comes closer, it is moved forward. Conversely, the minute hand moves back as world events improve. It has been moved 17 times in response to international events since its initial start at seven minutes to midnight in 1947:

1949 - The Soviet Union tests its first atomic bomb. Clock changed to three minutes to midnight (four minutes closer to midnight).
