It is official, the leap year is just not enough. Analysts have known for a while but fearing the worse that the worlds rotation is slowing down, even though life is speeding up, scientists need to find a way to keep everything in sync. With all of this in mind, the time lords in charge of this planet's official time system have decided to add an extra second into the year.
This time tampering is referred to as the leap second.
This is not some tomfoolery on April the 1st, nor is it February the 30th but it is going to happen tomorrow on June 30th this year.
