Hmm pa bas sad gledam online, i vidim da ima vise definicija za Jiffy. Jedna prica o fizici, druga o elektronici, a jedna o ovome sto sam ja rekao:
Sometimes a jiffy is used as a synonym for the Planck interval, about 5.4 × 10−44 seconds, which is the time it takes light to traverse the smallest meaningful length, the Planck length. In this quantum mechanical definition, a jiffy is the shortest theoretically possible time period that can be measured within one standard deviation of accuracy.
Toga se ja secam iz skole :)
