But this year, there is another addition to keep the secular calendar straight.
Not a month.
Not a day.
It's a second.
Reuters reports:
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.And why all the fuss?
The adjustment will be carried out by sticking an extra second into atomic clocks worldwide at the stroke of midnight Coordinated Universal Time, the widely adopted international standard, the U.S. National Institute of Standards and Technology said this week.
...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.
A leap second is added to keep uniform timekeeping within 0.9 second of the Earth's rotational time, which can speed up or slow down because of many factors, including ocean tides. The first leap second was added on June 30, 1972, according to NIST, an arm of the U.S. Commerce Department.
...Precise time measurements are needed for high-speed communications systems among other modern technologies.I'm counting the seconds.

It is good to know that someone is paying attention to all this.
