The Jargon File (version 4.4.7, 29 Dec 2003):

jiffy n. 1. The duration of one tick of the system clock on your computer (see tick ). Often one AC cycle time (1/60 second in the U.S. and Canada, 1/50 most other places), but more recently 1/100 sec has become common. ?The swapper runs every 6 jiffies? means that the virtual memory management routine is executed once for every 6 ticks of the clock, or about ten times a second. 2. Confusingly, the term is sometimes also used for a 1-millisecond wall time interval. 3. Even more confusingly, physicists semi-jokingly use ?jiffy? to mean the time required for light to travel one foot in a vacuum, which turns out to be close to one nanosecond. Other physicists use the term for the quantum-nechanical lower bound on meaningful time lengths, 4. Indeterminate time from a few seconds to forever. ?I'll do it in a jiffy ? means certainly not now and possibly never. This is a bit contrary to the more widespread use of the word. Oppose nano.
