2016 Will Be One Leap Second Longer

It would appear that 2016 will stay for somewhat longer this year—to be exact, one second more. The additional second being attached to the year is known as the jump second and it’s really not generally very uncommon. Since 1972, jump seconds have been added to the schedule each a few years, adding up to 26 changes barring the one coming up sometime in the evening. The explanation? To keep our nuclear checks in a state of harmony with the Earth’s rotation.

Peter Whibberley of the UK’s National Physical Laboratory clarifies :

“Atomic timekeepers are in excess of 1,000,000 times greater at keeping time than the turn of the Earth, which vacillates capriciously. Jump seconds are expected to forestall common time floating away from Earth time. Albeit the float is small—taking around 1,000 years to gather a one-hour difference—if not rectified, it would at last bring about tickers showing noontime before sunrise.”

Because the Earth’s revolution can be fairly flighty, these changes don’t come at customary stretches. Recently, the International Earth Rotation and Reference System Service delivered an announcement declaring that it is important to add an additional second toward the finish of December. Nonetheless, the last change was June 30, 2015 at 23:59:60 UTC.

As we noted in our article about nuclear timekeepers , extraordinary accuracy—even at an unbelievably small scale—is absolutely critical for dealing with specific frameworks (e.g., GPS) that depend on the coordinated overall precision of nuclear clocks. The expansion of the jump second assists with keeping up such systems.

Last year, our companions at Hodinkee expounded on the Hoptroff wristwatch —a timepiece that utilizes both mechatronic quartz and nuclear developments to naturally represent jump seconds.
