A positive leap second is to be introduced into the international time scale, Coordinated Universal Time (UTC), at the end of December 2005.

@ecs:
The extra second is to correct time to be the right... er... time.
(Puts on dr who hat so as to not loook like a complete ninny in this explaination)
As I understand it, because the earth does not always spin at a uniform speed, every now and again a "leap second" has to be added to the year to keep everything in check.
An american bunch whose name i forget want this abolished because atomic clocks are accurate and need to be adjusted because of this. Everyone else argues "thats fine, if you like "lunchtime" being about 6:30 in the evening one day because of uncorrected time building up" (ok that was more a bob the builder hat explaination)
Basically we never see that leap second, becauce it's there to account for a slight inaccuracy in the earths rotation.
I guess wikipedia can explain it more  |

1 day = 1 rotation of the earth.
This takes roughly 24 hours as measured by a highly accurate atomic clock.
Trouble is, the earth rotational speed is slowing down, therfore leap seconds are added every now and then so that we dont eventually end up with lunchtime at 6:30pm as mentioned above.

@meths
Yup, you're right. 23,400 leap seconds to be exact.
But excusing the exaggeration for a minute, you'd see the point though. Remember, Astronomy works in the thousands and millions of years.
@P900 lover
Yes, and the gap is slowly getting bigger as the earth slows down.
