A leap second will be introduced on 30 June 2012, according to the International Earth Rotation and Reference Systems Service (IERS) in Paris.
The leap second is needed to keep the super-accurate atomic clocks in sync with Solar Time, which changes very slightly over time due to very slight irregularities in the Earths rotation.
Leap seconds are very tightly controlled and can only fall on June 30 or December 31, as required. The last one was at the end of December 2008. This years event will happen after 11:59.59pm of June 30.
