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.

Nanoseconds

The nanosecond is a unit of time equal to one billionth of a second (10⁻⁹ s) and is the operational timescale of modern digital electronics. A 3 GHz processor executes approximately one clock cycle every 0.33 nanoseconds. The propagation of electrical signals through circuits, memory access times, and network packet transmission are all measured in nanoseconds. Light travels approximately 30 cm in one nanosecond.
