Modern use

Modern-use scope is context-dependent; the website should follow the record's current-status and regional/system labels rather than imply universal use.

Did you know?

A physics 'jiffy' is spectacularly shorter than an everyday jiffy: the light-centimetre definition is only about 33.36 picoseconds. Computing and electronics have used completely different jiffies.
