The leap second

The earth rotation is gradually slowing due to drag caused by tides so scientist came up with a crafty solution. Every few years they adjust UTC by adding an extra second to either June 30th, or December 31st. Ever since the atomic clock has been used to coordinate world time, a total of 33 leap seconds have been added.

Haha! April fools. This actually happens.
