You may remember June 30th, 2012 when the scientific universe decreed that an extra second needed to be added to the year to account for the slowing of the earth's rotation around the sun. This Leap Second allowed the hyper accurate atomic clocks which run on International Atomic Time (TAI) to resync with Universal Time (UT1) which is defined by the rotation of the Earth. Well this year, on Tuesday June 30th we are getting another one.
