Sunday to be one second longer than normal.
June 30 will have one extra second added to the end of the day, in an effort to keep the worlds atomic clocks in sync with the irregular wobbles of the Earth.
23:59:60 will be added due (mostly) to the 1.4 milliseconds per day per century of braking action that the tides provide on the Earth’s rotation. The last leap second was in 2008.
The adjustments are decided by the International Earth Rotation and Reference Systems Service. While some groups have called for leap seconds to be scrapped, a meeting on the issue last January couldn’t come to any agreement, and the group will revisit the matter again in 2015.
This weekend longer by 1 second? Sure, will do…
