Procedure
Time-of-day synchronization with NTP server
1. Click in the "NTP Client" check box to enable the automatic time setting using NTP.
2. In "Time Zone", enter the local time difference to world time (UTC).
The input format is "+/-HH:MM" because the NTP server always sends UTC time, for
example +02:00 for CEST, the Central European Summer Time. This time is
recalculated and displayed as the local time based on the specified time zone.
3. Select the "NTP Server Index".
4. Click the "Create" button.
A new row is inserted in the table for the NTP server.
5. In "NTP Server Address", enter the address of the NTP server whose frames are used
to synchronize the time of day.
6. In "NTP Server Port", enter the port via which the NTP server is available. The port can
only be modified if the address of the NTP server is entered.
7. In the "Poll Interval" column, enter the interval in seconds after which a new time-of-
day query is sent to the time server.
8. Click the "Set Values" button.
Time-of-day synchronization via a secure NTP server
To synchronize the time of day via a secure NTP server, the following additional steps
are necessary:
1. Click the "Secure NTP Client only" check box to enable the automatic time setting using
Secure NTP.
2. Configure the authentication.
– In "Key ID" enter the ID of the authentication key.
– In "Hash Algorithm" select the required format.
– In "Key" enter the authentication key.
With these entries, the NTP client authenticates itself with the secure NTP server.
These entries must be present on the secure NTP server.
3. Click the "Set Values" button.
