Enjoy An Extra Second On June 30th!

Time keeps on slipping, slipping, slipping into the future.

This is way above my pay-grade, so I'll let this video from NASA explain why June 30th 2015 will actually be 86,401 seconds long instead of 86,400.

If you didn't click the link above, let me try to dumb it down (for myself as much as anyone).

Earth’s rotation is gradually slowing down. We are able to tell this thanks to those VLBI things the video talked about. We round off to say that a day is 24 hours, or 86,400 seconds...BUT a day is really 86,400.002 seconds.  Point zero zero two seconds is insignificant on its own, but when you start to add up across an entire year, it turns into almost a whole second. Again, one second isn't much in regards to our daily life, but for scientific purposes, it can be a lot.
