Network Time Protocol (NTP)

The NTP public domain software from the University of Delaware is included in the Oracle Solaris software. The ntpd daemon sets and maintains the system time of day. The ntpd daemon is a complete implementation of the version 4 standard, as defined by RFC 5905.

The ntpd daemon reads the /etc/inet/ntp.conf file at system startup. See the ntp.conf (4) man page for information about configuration options.

    Remember the following when using NTP in your network:

  • The ntpd daemon uses minimal system resources.

  • An NTP client synchronizes automatically with an NTP server when it boots. If the client becomes unsynchronized, the client resynchronizes again when the client contacts a time server.
