3.1 SNTP configuration
55
Note: If you have enabled PTP at the same time, the SNTP client first
collects 60 time stamps before it deactivates itself. The device thus
determines the drift compensation for its PTP clock. With the preset server
request interval, this takes about half an hour.
Note: If you are receiving the system time from an external/redundant server
address, switch off the reception of SNTP Broadcasts (see “Accept SNTP
Broadcasts”). You thus ensure that the device only takes the time from a
defined SNTP server.
