2015 will be one second longer than normal year. Scientists announced that the thirtieth of June 11:59:59 will be added one more second in the hours UTC (Coordinated Universal Time). That is, we have a chance to see the numbers on the clock 11:59:60. And all because the Earth moves a little slower testimony of our super-accurate atomic clocks and indications of time desynchronizes with reality. Time Atomic Clock - constant. But every day the Earth slows down its rotation, about two-thousandths of a second, and the actual day is getting longer, as long as we continue to believe that it is equal to twenty-four hours. Therefore, this day is 86,401 seconds instead of 86,400.
