5.4 SNTP
SNTP allows a network entity to communicate with time servers in the network/Internet to retrieve and synchronize the time
of day information. When this feature is enabled, the system attempts to retrieve the time of day information from the
configured time servers (primary or secondary); and when successful, it updates the relevant time objects in the system.
