[arm-allstar] Redefining the NTP source

[David McGough]

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.
