The nonprofit Internet Systems Consortium, Inc. (ISC) maintains sites that automatically return lists

of public time servers to an NTP client such as the Image Server. Hence, the NTP Servers field is

initially filled in with the URL’s for these sites (0.pool.ntp.org, for example). Of course you can

overwrite this list with the addresses of specific time servers you may want to use. However, if you

try to clear the NTP Servers field it will be reset to the default list.

Note: When URLs (non-numeric site address such as pool.ntp.org) are used in the NTP Servers

field, you must provide the IP address of at least one DNS (Domain Name Server) in the Name

Servers field. Typically, this address is supplied by your Internet Service Provider.

These name servers translate URL names into numeric IP addresses needed to access the sites in

question.

If you are using a GPS-based time server for instance, that is connected directly to your local area

network, enter its numeric IP address (such as 192.168.1.60) into the NTP Servers field, leaving the

Name Servers field blank.

Also, if you know the numeric IP addresses of the public or corporate time servers on the Internet,

you can enter these addresses, separated by spaces, in the NTP Servers field, leaving the Name

Servers field blank, since there would be no URLs to be resolved.

Note: Not all Time Servers allow unlimited public access. Refer to www.ntp.org for more

information.
