Lecture Recorder x2 User Guide
Clicking Enable Time Synchronization on the Date and Time page, results in the date
and time being received from a public network time protocol (NTP) server. This is
done by having the Lecture Recorder x2 connect to the server over the Internet. NTP
uses UDP and port 123. The default NTP server is time.nrc.ca. This should be
changed to a NTP server that is recommended for your location. This information
should be available from your network administrator.
For more information about NTP, including a list of recommended NTP servers, refer
to the following webpage: The NTP Public Services Project.
To get the correct time from the NTP server, ensure that the correct Time Zone for
the location of the Lecture Recorder x2 is selected.
If the Lecture Recorder x2 device cannot connect to the Internet and there is an
RDATE server on the network, you can set time synchronization to use RDATE (as
defined by RFC 868). Contact your network administrator for the address of the
RDATE server and enter the RDATE server IP address into the Server IP Address field.
In both cases, how often the date and time is updated can be configured. The Time
Update interval can be every 1, 6, 12, or 24 hours.
