2016 to last a second longer than other years
The countdown to New Year this year will take one second longer than usual as clock experts will compensate for a slowdown in the Earth's rotation. The 'leap' second will be introduced after 23:59:59 by National Physical Laboratory on December 31. The 'leap' second, added for the 27th time, is necessary due to unpredictable changes in the Earth's rotational speed.
