Clock drift refers to several related phenomena where a clock does not run at the exact right speed compared to another clock. That is, after some time the clock "drifts apart" from the other clock. This phenomenon is also used for instance in computers to build random number generators. On the negative side, clock drift can be exploited by timing attacks.

Famous quotes containing the words clock and/or drift:
“Stands the Church clock at ten to three?
And is there honey still for tea?”
—Rupert Brooke (1887–1915)
“To drift with every passion till my soul
Is a stringed lute on which all winds can play,
Is it for this that I have given away
Mine ancient wisdom, and austere control?
Methinks my life is a twice-written scroll
Scrawled over on some boyish holiday”
—Oscar Wilde (1854–1900)
