Leap Seconds
NTP delivers UTC time. UTC is subject to scheduled leap seconds to synchronize the timescale to the rotation of the earth. When a leap second is added, NTP is suspended for 1 second. Because NTP has no mechanism for remembering the history of leap seconds, leap seconds cause the entire NTP timescale to shift by 1 second.

Famous quotes containing the words leap and/or seconds:
“Athletes have studied how to leap and how to survive the leap some of the time and return to the ground. They don’t always do it well. But they are our philosophers of actual moments and the body and soul in them, and of our manoeuvres in our emergencies and longings.”
—Harold Brodkey (b. 1930)
“At this very moment,... the most frightful horrors are taking place in every corner of the world. People are being crushed, slashed, disembowelled, mangled; their dead bodies rot and their eyes decay with the rest. Screams of pain and fear go pulsing through the air at the rate of eleven hundred feet per second. After travelling for three seconds they are perfectly inaudible. These are distressing facts; but do we enjoy life any the less because of them? Most certainly we do not.”
—Aldous Huxley (1894–1963)
