Earth Has Leap Second 1st July 2012 - Did You Make The Most Of It?

Time is precious and since the Earth had a leap second on 1st July 2012 where an extra second has been added by timekeepers, I hope you made the most of it! How did you spend that extra second? Changing the world?

I wonder if all clocks are automatically adjusted?

Saturday night (Sunday morning AEDT) will stretch longer by a second. A leap second.

International timekeepers are adding a second to the clock at midnight universal time Saturday, June 30, going into July 1. That's 8pm EDT Saturday (1000 AEDT Sunday). Universal time will be 11:59:59 and then the unusual reading of 11:59:60 before it hits midnight.

A combination of factors, including Earth slowing down a bit from the tidal pull of the moon, and an atomic clock that's a hair too fast, means that periodically timekeepers have to synchronise the official atomic clocks, said Daniel Gambis, head of the Earth Orientation Service in Paris that coordinates leap seconds.

The time it takes the Earth to rotate on its axis - the definition of a day - is now about two milliseconds longer than it was 100 years ago, said Geoff Chester, spokesman at the US Naval Observatory, keeper of the official US atomic clocks. That's each day, so it adds up to nearly three-quarters of a second a year.

Timekeepers add that leap second every now and then to keep the sun at its highest at noon, at least during standard time. This is the first leap second since January 2009 and the 25th overall. Gambis said the next one probably won't be needed until 2015 or 2016.

There should be no noticeable affect or inconvenience on computers or any other technology that requires precise timekeeping because they adjust for these leap seconds, Gambis said Friday.

Earlier this year, official timekeepers from across the world discussed whether to eliminate the practice of adding leap seconds. They decided they needed more time to think about the issue and will next debate the issue in 2015.
So for now, Chester said, "you get an extra second, don't waste it."
