sysconf ntp addserver
Add an NTP server. NTP will automatically synchronize with the highest-stratum server you add. If none of these servers are accessible, NTP will synchronize with the local clock, and may be subject to drift.
A DNS name server must be configured if you add an NTP server by hostname.
