Happy New Year!
For those keeping track, you may have noticed that 2005 felt a little longer than normal. As it turns out, you're right. 2005 was one second longer than normal.
The earth, it's a-slowin' down it seems. The minute before midnight in Greenwich, England was extended to 61 seconds as the 'leap' second was added.
Very peculiar. So, welcome to the New Year, and make sure you set your clocks one second back.
