Later tonight, everyone on earth will be granted a little extra time as International Timekeepers will be adding one second to Saturday night. Clocks will have the unusual reading of 11:59:60 before going to 12:00am. What are you going to do with your extra free time?
The timekeeper say this is needed to adjust for earths slowing rotation due to tidal effects of the moon (which is slowly getting closer to earth) and our atomic clocks (the most accurate timeclock available to humans) are running just a tad fast.
Earlier this year time keepers from around the world met to decide if they still need to add the leap time or not, but ultimately decided they needed more time to decide. Therefore, tonight's adjustment will go forward.
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 U.S. Naval Observatory, keeper of the official U.S. 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.
