System clocks
Nodes running Appliance Containers must be configured for clock synchronization through NTP with other Nodes in the system.
The host OS should synchronize to the same NTP server as the remainder of the system.
CAUTION:
Unlike the Manager Appliance, the Manager Container cannot provide NTP
synchronization services. Devices that are managed by a Manager Container must be configured
to use an external NTP server.
Note: For more information on NTP synchronization, see Configure clock synchronization and the documentation for the preferred NTP client.
