12.8.1.1 SNTP
Selecting Sync with SNTP Server from the drop down opens the SNTP Server
Address box where the server automatically receives time updates, which can
be configured. See
http://www.pool.ntp.org/en/
for a list of publicly available
time servers.
The configuration of an SNTP server provides a means of synchronizing the
onboard clock of the CCFC with the specified SNTP server. This ensures that
the camera clock is always accurate. It is also possible to configure a time zone
offset for the camera.
Other than the address of the SNTP server, the time zone needs to be selected
and the Adjust for DST (daylight savings time) can also be selected.
