2015 longer by a leap second

At 23:59:60 UTC on June 30, 2015, a Leap Second will be added, making this day last for 86401 seconds instead of the usual 86400. This practice started in 1972 and since then a total of 25 leap seconds were added to the UTC time, last one in 2012. Correction of each UTC leap second is usually decided about six months in advance by the International Earth Rotation and Reference Systems Service (IERS).
