[arm-allstar] Redefining the NTP source

[w2put at sbcglobal.net]

Howdy folks, here's an update in the event you are interested. After pondering my options I decided to persue the RTC. I found the one that Dave shared a link to also available on Amazon, but I didn't feel like waiting till February, so I ordered another version that didn't have the easy plug on header. The no header actually works best for me in this particular case.
Using the script info that Dave so kindly shared a link to, some really good guessing, and enlisting the help of the Google, I eventually figured out what to actually do with the information. Scripts aren't exactly something I'm even remotely skilled at.
After a couple hours of messing around I got it working on the desk in a test environment. I'm now very confident that I can easily repeat that in the field. So hopefully within the next week or so I'll have time to get to the site and implement it. Since it will have been more than an hour between figuring it out and implementing in the field I made sure to document how I did it because I knew I wouldn't remember exactly what I did if I didn't write it down. If anyone is interested in the doc I'll be happy to share it.

Hi Dan,

None of the RPi boards include a Real Time Clock.  So, as you realize, 
another source is needed.  The simplest, inexpensive, solution is a 
battery RTC, such as this type:

This same basic board is available from many sources, the above listing 
just being one example.

I've got perhaps a dozen of these RTC boards installed and they work 
pretty well, a few seconds a month drift--obviously not as good as GPS, 
but they're really simple and usually "good enough."

A setup script is here:

If you really need a precision time source, many little GPS boards are 
available. If this is the direction you're wanting to go, I dig up links 
to boards I've used?

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.
