3.5 NTP Configuration

Network Time Protocol (NTP) is an Internet standard protocol that assures accurate

synchronization of computer clock times to the millisecond in a network of computers. Based

on UTC, NTP synchronizes client workstation clocks to the U.S. Naval Observatory master

clocks in Maryland, Washington D.C., and Colorado Springs, CO. If enabled, Venus

DataStreamer will send periodic time requests to the selected server.

1. Click the File drop-down menu and click Configuration. The main configuration

window will appear.

2. Click NTP Configuration.

3. Type the NTP server in the area provided. Note: To find the correct NTP server, go to

http://tf.nist.gov/service/time-servers.html

4. If desired, check the box by Update Automatically and set the frequency that the

clock should synchronized.

5. Click Apply to make changes take effect.

Note: If the PC running Venus DataStreamer is located behind a firewall or proxy server

on the network, it may be necessary to open Port 123 in order for NTP synchronization to

occur.

If this is not possible, an internal server will need to be configured. Consult the local

network administrator for more information.
