Use it wisely!

The keepers of the world's clocks are adding a "leap second" to time at the stroke of midnight, Saturday June 30th.  For one second, time will stand still as scientists give atomic clocks the chance to catch re-synch with Earth.

Today's atomic clocks are accurate to approximately one second in 200 million years. On average, our planet has been falling behind atomic time at a rate of about two milliseconds per day. As a result, it now trails the "official" clock by about six-tenths of a second.

Once completed, Sunday morning will find the Earth about a fourth of a second ahead of the clock - which will allow for the growing time difference.
