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.
