LEAP SECOND?

THERE'S GOING TO BE A "LEAP" SECOND ON NEW YEAR'S EVE:

You know how every four years we tack on an extra day at the end of February? That's right . . . leap year. Well, the reason we have leap year is because it takes the Earth a little bit more than 365 days to travel around the sun. In fact, it takes the Earth exactly 365.2422 days to travel around the sun. But since a year is only 365 days long, we have to add an extra day every four years to fix the calendar.

Anyway, the same principle applies to Earth's rotation. Every now and then, we have to add a "leap second" to keep our clocks correct. So why am I bringing this up? Because on New Year's Eve, a leap second will be added to the clock just before 7:00 P.M. Eastern. (Live Science)
