Time Synchronization and NTP Service

When hosts are powered on, their clocks synchronize to the NTP server when the system is configured to listen to NTP multicast (the default). If the hosts and SPs use the same NTP server, events logged in Oracle Solaris and on the SP can be correlated based on their time stamps. If the hosts and SPs use different NTP servers, their times might drift, and correlating log files could become difficult. If you connect a domain to an NTP server other than the one used by the SP, ensure that both are low-stratum NTP servers that provide the same degree of accuracy.
