Jiffy (time)

Jiffy is an informal term for any unspecified short period of time, as in "I will be back in a jiffy". From this it has acquired a number of more precise applications for short, very short, or extremely short periods of time. First attested in 1785, the word's origin is unclear, though one suggestion is that it was thieves' cant for lightning.

Beginnings in measurement

The earliest technical usage for jiffy was defined by Gilbert Newton Lewis (1875–1946). He proposed a unit of time called the "jiffy" which was equal to the time it takes light to travel one centimeter in a vacuum (approximately 33.3564 picoseconds). It has since been redefined for different measurements depending on the field of study.

Uses

In electronics, a jiffy is the period of an alternating current power cycle, 1/60 or 1/50 of a second in most mains power supplies.

In computing, a jiffy was originally the time between two ticks of the system timer interrupt. It is not an absolute time interval unit, since its duration depends on the clock interrupt frequency of the particular hardware platform.
