Device Time shows the current time setting of the recorder. It cannot
be edited here.
Set Time lets you specify a time that you want to use. As soon as
you press OK , the system time resets to that time.
Alternatively, you can click Sync. with computer time . When you
click the checkbox, the recorder communicates with the network
computer and adjusts its time to match. Although the box remains
checked, this synchronization happens only once (the box becomes
unchecked when you leave this screen).
Enable DST
This works with both NTP and manual time settings.
By default, daylight saving time is enabled. If your location does
not observe daylight saving time, click this box to remove the check
mark and disable DST adjustment.
The Start Time and End Time boxes let you set the month, week,
day, and hour (in 24-hour time) that daylight saving time starts and
ends. The DST Offset box sets the amount that the time changes.
As of 2015 in the most of the US and Canada, daylight saving time
starts on the second Sunday in March and ends on the first Sunday
in November. The switch takes place at 2:00 a.m. local time, and the
offset is 60 minutes. Thus, with a few exceptions noted below, you
can keep the default settings.
Places that do not observe daylight saving time include Arizona
(outside of Navajo territory), Hawaii, Saskatchewan, and a number
of local exceptions across Canada. For Arizona and Hawaii, just
disable DST. For Saskatchewan, disable DST and set your system to
Central Time (at the top of the window). For other exceptions, check
local regulations.
