Address box where the server automatically receives time updates, which can

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.
