The world’s 26th leap second ever will be added this year, on June 30, 2015, when the second hand of the clock will essentially strike midnight twice.

Usually, systems around the world stay in sync with each other using a system called the Network Time Protocol, which is programmed to stay within a few milliseconds of Coordinated Universal Time—the official scientific time for the world as measured by atomic clocks. But the protocol doesn’t deal well with leap seconds.
