A leap second will be added to the clock at 12/31/2008 23:59:59 UTC tonight. Clocks will go:
12/31/2008 23:59:58
12/31/2008 23:59:59
12/31/2008 23:59:60
01/01/2009 00:00:00
01/01/2009 00:00:01
Hopefully most IT folks will be otherwise occupied at that time and not focusing on their system clocks.
Have a Happy 1-second Delayed New Year.
