Synopsis # Accurate system time is essential for logging, cryptographic protocols, file timestamps, and consistent operation of distributed systems. OpenBSD includes a secure, minimalist NTP daemon, ntpd(8), in the base system. This service allows the system clock to be synchronized with remote time servers and, optionally, to provide time synchronization to other systems. This chapter describes how to configure ntpd(8) for typical client use and for serving time to a local network.
