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.

Microseconds

The microsecond is a unit of time equal to one millionth of a second (10⁻⁶ s) and represents the timescale of analogue electronics, radio transmission, and chemical reactions. A lightning bolt typically lasts about 200 microseconds. In computing, memory latency (the time to read from RAM) is typically 50–100 nanoseconds, while disk seek times are measured in milliseconds — making the microsecond a transitional scale in digital systems.
