Important Considerations

SNTP handles the synchronization of system clocks in the network to the national time standards via distributed time servers.

Your system provides the SNTP client.

The display has two types of information:

Configuration information — User configurable parameters appear.

Servers information — Information returned by the server

appears if you have defined SNTP servers. Otherwise, the No message appears.
