A gift of time

Item:

Time will stand still for one second this evening (June 30) as a "leap second" is added to Coordinated Universal Time (UTC), the time standard by which most clocks are regulated. The International Earth Rotation and Reference Systems Service (IERS), which keeps track of time for the world, has decided that the extra second is needed to deal with Earth's irregular but gradually slowing rotation.
