ntpd (Network Time Protocol daemon)

The Network Time Protocol daemon (ntpd) is software that runs on computers to keep their clocks accurate by regularly syncing with official time sources over the internet. It ensures that the system time matches the precise time provided by trusted servers, which is essential for coordinating activities, logging events, and maintaining consistency across systems. By continuously adjusting the clock, ntpd helps prevent errors caused by clock drift, ensuring time-sensitive operations are reliable and synchronized across networks.
