We’re all getting an extra second on June 30 this year

This year will be one second longer than 2014. Scientists have announced that they’ll be adding an extra second, called a “leap second” to the UTC (coordinated universal time) clock on June 30 at 11:59:59.

That means the clock will read 11:59:60. This is because the Earth is moving a little slower than our super-accurate atomic clocks dictate, and it’s getting out of sync. In fact, while atomic time is constant, the Earth’s rotation is slowing down by around two thousandths of a second each day.

“The real simple explanation is the Earth is slowing down a little bit,” Nick Stamatakos, the head of the Earth Orientate Parameters at the US Naval Observatory told the Australian Broadcasting Corporation.

“For that day there’ll be 86,401 seconds, instead of 86,400 seconds,” he told The Telegraph.
