TIMED(8) System Manager's Manual TIMED(8)

timed — time synchronization daemon

timed takes no arguments, and users should not launch it manually.

timed maintains system clock accuracy by synchronizing the clock with reference clocks via technologies like NTP. Inputs are merged inside of timed, where it calculates uncertainty to facilitate scheduling proactive time jobs. timed is also aware of power/battery conditions.
