Configuration restrictions and guidelines
A device can act as a server to synchronize the clock of other devices only after its clock has been
synchronized. If the clock of a server has a stratum level higher than or equal to that of a client's clock,
the client will not synchronize its clock to the server's.
The synchronization process takes a period of time. Therefore, the clock status might be unsynchronized
after your configuration. In this case, you can refresh the page to view the clock status later on.
If the system time of the NTP server is ahead of the system time of the device, and the difference between
them exceeds the Web idle time specified on the device, all online Web users are logged out because
of timeout.
