Description of SNTP

The Simple Network Time Protocol (SNTP) enables you to synchronize the
system time in your network.
The device supports the SNTP client and the SNTP server function.
The SNTP server makes the UTC (Universal Time Coordinated) available.
UTC is the time relating to the coordinated world time measurement. The
time displayed is the same worldwide. Local time differences are not taken
into account.
SNTP uses the same packet format as NTP. In this way, an SNTP client can
receive the time from an SNTP server as well as from an NTP server.
