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.

“Never try to leap from a standstill.”
—Mason Cooley (b. 1927)
“You have known your friend so long and loved him so much, and then all of a sudden you are so mad at him, you say, I could just kill you and you still like each other, because you have always been friends and you know in your mind you are going to be friends in a few seconds anyway.”
—Anonymous Twelve-Year-Old. As quoted in Children’s Friendships by Zick Rubin, ch. 3 (1980)
