Minute with 61 seconds

On December 31, a leap second will be added. Leap seconds are added in order to keep atomic clocks and the earth's rotational time in synch. There have been others since they began in 1972. So, right before midnight on December 31 (which is 7pm on the east coast of the US), clocks will read 23:59:60 before changing to 0:00:00 of 2006.

More Info: I, II
Enjoy.
