A little pedantic nitpick: no there isn't, that was caused by an initial misreading of the definition of leap seconds. There *can* be two leap seconds in a year (which is what caused the confusion), but if that happens one will be at the end of June and the other at the end of December, they'll not happen together. Theoretically it's possible to have a negative leap second, but as that would require the Earth's core to collapse enough to spin it faster or a hit from a massive impactor, I'd rather not be around to see it. :-} -- In the dungeons of Mordor, Sauron bred Orcs with LOLcats to create a new race of servants.
