7.2.1 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.
The SNTP client obtains the UTC from the SNTP server.
