Leap second

For those of us trying to cram one more thing into a busy schedule, this is our lucky year. The masters of time are is giving us 86,401 extra seconds. Most of it comes on Feb. 29 to mark leap year. Then, on June 30, we get an extra tick to get the world’s rotation and our atomic timepieces (accurate to one second in 100 million years) back in sync. Leap seconds have occurred 24 times, the first one on June 30, 1972.
