The International Earth Rotation and Reference Systems Service in 1972 set "leap second" phenomenon. A leap second is a one-second adjustment that is occasionally applied to Coordinated Universal Time (UTC) in order to keep its time of day close to the mean solar time, or UT1. Without such a correction, time reckoned by Earth's rotation drifts away from atomic time because of irregularities in the Earth's rate of rotation. The necessity of adding leap seconds is caused not sufficient accuracy designation in the 50s, the length of the solar day and the resulting length of a second, changes in Earth's rotation period due to unforeseeable factors, such as mass movements in the interior of the Earth, and constant deceleration speed of Earth's rotation caused by friction masses of earth and water during tidal.The most recent one happened on was inserted at the end of June 30, 2015 at 23:59:60 UTC
