Do you need more time to celebrate the New Year? Get ready for a minute with 61 seconds. Scientists are delaying the start of 2006 by the first "leap second" in seven years, a timing tweak meant to make up for changes in the Earth's rotation.

The adjustment will be carried out by sticking an extra second into atomic clocks worldwide at the stroke of midnight. Enjoy New Year's Eve a second longer. You can toot your horn an extra second this year.

Coordinated Universal Time coincides with winter time in London. On the U.S. East Coast, the extra second occurs just before 7 p.m. on New Year's Eve. Atomic clocks at that moment will read 23:59:60 before rolling over to all zeros.
