Today's Fact Of The Day (FOTD) is Leap Seconds:
The rotation of the Earth is slowing down.This means that a solar day(the time it takes Earth to make one complete revolution)and the time shown by atomic clocks would gradually diverge. This problem has been solved by "leap seconds" . There have been 22 leap seconds since 1972. The last one was added on 31 December 2005 , which delayed new year's day 2006 by one second!
