Seconds

The second is the SI base unit of time, defined since 1967 as the duration of exactly 9,192,631,770 cycles of radiation from the caesium-133 atom. Atomic clocks based on this definition lose less than one second in 300 million years. The second underpins all timekeeping in modern civilisation — from GPS satellite synchronisation to internet protocols and financial transaction timestamps.

Fortnights

A fortnight is a unit of time equal to exactly 14 days (1,209,600 seconds), or two weeks. The word is a contraction of "fourteen nights" from Old English. It is still widely used in British English, particularly in employment law (wages paid fortnightly), rental agreements, and magazine publication schedules. The fortnight has no equivalent single word in most other languages, making it a distinctly British measurement unit.
