Whether you can feel it or not, the Earth’s rotation is slowing. So much so, that on June 30, as the world’s atomic clock hits 11:59, a 60th second will tick before the clock strikes midnight. It’s called a leap second. And it’s being implemented in order to adjust time to the rotation of the Earth. While this might sound like simple science, it’s got some Internet companies a bit concerned about their computer systems and how the time change, although brief, might affect their servers. We talk with John Lowe from the National Institute of Standards and Technology about the threat of an Internet crash circa the Y2K scare of 1999 and how some tech companies like Google are preparing themselves.(Flickr/IronRodArt - Royce Bair)
