7.3 Date/Time

The "system time" setting is used by the unit for synchronizing scheduling services and system logging

activities. You will need to set the time zone corresponding to your location. The time can be set manually

or the device can connect to a NTP (Network Time Protocol) server to retrieve the time. You may also set

Daylight Saving dates and the system time will automatically adjust on those dates.

NTP (network time protocol) is a protocol that allows local computers to synchronize the clocks. When a

NTP client initiates a time request exchange with the NTP server, the client can adjust its local clock to

exactly match the clock at the server’s computer. Accurate time information is critical for monitoring the

device with system log. The device will synchronize itself with an external NTP server automatically

When one of the following conditions occurs:

9 Rebooting the device

9 The Expires time having run out

You will need to set the time zone corresponding to your location. The time can be set manually or the

device can connect to a NTP server to retrieve the time. You may also set Daylight Saving dates and the

system time will automatically adjust on those dates.

Note: The Time Zone does not adjust automatically to the North America daylight saving time.

Adjust the value manually when needed. -4 is the time zone with daylight saving and -5 is

without daylight saving. The value can also be modified through the configuration file.
