We are having problems with timing on some of our servers. They use NTP clients with Web-based servers, but it varies from true time by as much as 5 seconds from day to day. That’s unacceptable in the radio business.
I have a known good GPS at all of my transmitter sites that’s disciplined and accurate to within 1 nanosecond, but I’m having trouble finding software to set up the NTP server that uses it. A Google search on “ntp server” gives zillions of hits on how to USE an existing NTP server to set the time on your own PC with a client, but very little practical, “how-to” walk-through information on setting up an NTP server for your own use. I have found almost nothing on using my GPS to sync the NTP.
Any ideas? Or do I need to look for a hardware solution? This NTP server will only be exposed in-house on a private network. I won’t be exposing it to the Internet at large.
