Network Time Protocol (NTP)

Observe the following guidelines for NTP:

  • Synchronization – The primary requirement when you configure NTP, or any time synchronization facility within the cluster, is that all cluster nodes must be synchronized to the same time.

  • Accuracy – Consider accuracy of time on individual nodes to be of secondary importance to the synchronization of time among nodes. You are free to configure NTP as best meets your individual needs if this basic requirement for synchronization is met.

See the Oracle Solaris Cluster Concepts Guide for further information about cluster time. For more information about NTP, see the ntpd(1M) man page that is delivered in the Oracle Solaris service/network/ntp package.
