A Faster Spinning Earth May Cause Timekeepers to Subtract a Second from World Clocks
Earth’s changing spin is threatening to toy with our sense of time, clocks and computerized society in an unprecedented way — but only for a second. For the first time in history, world timekeepers may have to consider subtracting a second from our clocks in a few years because the planet is rotating a tad faster than it used to. Clocks may have to skip a second — called a "negative leap second" — around 2029, a study in the journal Nature said Wednesday.
