[arm-allstar] Redefining the NTP source

[w2put at sbcglobal.net]

I have a repeater that is at a site with no normal internet, just when I'm on site for service and have a hot spot available. So last week while doing service I ran an update and it fixed the time announcement, and when I say fixed I really mean broke it because I had it disabled. The standalone Pi can't keep an accurate clock for anything, and now it's back announcing the time. Right or wrong. I can't find the details on how to unfix it again.
So what I was thinking of doing is using either a local Spectracom GPS Netclock for NTP via Ethernet or a USB GPS. Anyone know if and how either could be done? I kinda like having the time, but unless I can get a local NTP I'll have to figure out how to disable it again.

Thanks in advance,Dan W2PUT
