What This Year's Extra Second Could Mean For The Internet
Chunks of the Internet went offline in 2012, the last time scientists added an extra second to clocks to match Earth's slowing rotation.By Matt Moreno | January 7, 2015
If you've got plans June 30, then you'll have a little extra time to attend. A whole extra second, to be exact.
No, 2015 isn't a leap year, but we will see a leap second.
The decision to add an extra second to June 30 comes from the International Earth Rotation Service in Paris. The Earth's rotation is gradually slowing, so to sync up those atomic clocks most accurately, an extra second needs to be added every few years. (Video via NASA)
