From The Jargon File (version 4.4.7, 29 Dec 2003) :
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
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. See also Real Soon Now.

for light to travel one foot in a vacuum, which turns out to
be close to one *nanosecond*.
