entry fields [hh:mm:ss] or automatically by the master clock which itself has to be syn-
chronized to UTC time beforehand. To activate the synchronization, tick the checkbox
activate NTP and enter hostname or IP address of your server. When NTP is activated
the ART controller is trying to connect to the NTP server repeatedly in order to update its
clock. As a measure of quality for the connection to the NTP server check its ’reachability’.
The values can range from 0% to 100 %, with higher values showing good connection.
Furthermore the quality of the synchronization of the master clock and the ART con-
troller’s internal clock is indicated by the ’estimitated precision’ in the unit milliseconds
(=ms).
Z
Complete synchronization with NTP servers usually takes some time.
In case of large differences between master clock and local time client
the clock may be updated immediately but complete synchronization
will still take some additional time.
i
Synchronization with NTP servers does not affect active measure-
ments.
i
In general it is recommended to synchronize with a local master clock
rather than directly to a remote time server on the internet. This re-
duces network latency and jitter, conserves bandwidth and limits the
load on public time servers.
