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

Connect to the Admin

Interface

.

 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

http://support.ntp.org/bin/view/Servers/WebHome

.

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considered obsolete and has been replaced by NTP.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.
