4.4.10.7 NTP server
On this WBM page, you configure the device as an NTP server or as an NTP server of the
type "NTP (secure)". The other devices can call up the time made available by the device
via this NTP server. This means that the supplied devices are not dependent on a
connection to an external time server.
Note
Time synchronization
Also configure the device as NTP client so that it synchronizes the connected devices to
a correct time. As NTP client, the
device gets the precise time from an external time
server and as NTP server distributes it to its NTP clients.
The NTP server does not send cyclic messages with time information on its own, but
only responds to corresponding requests. Settings in the funct
ion as a client (time zone
and daylight saving time) do not influence the time information that the device sends as
a server.
