Configure Synchronized Time (NTP, PTP v1, and RDATE)
By default the Networked VGA Grid uses the network time protocol server (NTP server) protocol and a time
server from National Research Council Canada. You can continue to use this time server or configure a new
server that is more appropriate for your network and location. Your system administrator can provide the
correct time synchronization server settings.
To set the time synchronization method:
1. Connect to the admin interface using your preferred connection mechanism. See
.
2. Login as admin.
3. Select the Date and Time link in the Configuration menu; the date and time configuration page opens.
4. Click the Enable time synchronization radio button if it is not already selected.
5. Choose one of the following choices from the Protocols drop down:

Description/Options
NTP
Network Time Protocol (NTP) is used for clock synchronization over the internet.
There are many publicly available NTP servers you can use, or your company may
have its own NTP server. For more information about NTP and to find NTP servers,
refer to
RDATE
RDATE is a tool for querying the current time from the network. It is generally
considered obsolete and has been replaced by NTP. It's offered here for
backwards compatibility with older timekeeping systems.
PTP v1
The Precision Time Protocol (PTP) is used for clock synchronization over the
internet. It has clock accuracy in the sub-microsecond range, making it more
granular than NTP.
6. Tailor the synchronization protocol with the required parameters as described below.
7. If NTP is selected:
a. Enter the IP address or server name for the NTP server in the Server IP Address field.
