If we didn’t add an extra second to the clock, sometime a few million years from now, humans or their descendants will sleep till noon. But for now, it’s a real stress on may business who worry their websites may crash — and Google’s trying to block it.
Cool!!! - Clock enthusiasts take note: A leap second has been scheduled for June 30, 2012. A leap second is an adjustment to the atomic clock-based Coordinated Universal Time (UTC) to bring it more closely in line with Universal Time (UT), which is based on the rotation of the earth. The two time standards do not agree because the earth’s rotation is ever so gradually and unpredictably slowing down. Yes, really.

Leap seconds don't come on a regular schedule because Earth's rotation varies, says Demetrios Matsakis, chief scientist for time services with the United States Naval Observatory in Washington D.C. Our planet is slowing down, but it does so in unpredictable ways. So some periods require more leap seconds than others. http://news.nationalgeographic.com/2015/06/150629-leap-second-atomic-astronomical-time-earth-rotation-physics/
