[arm-allstar] Adding a Real Time Clock to the BBB

[Mike / W5JR]

Doug, I'm guessing you were referring to my issue with the NTP access. I did get it working. I found a file somewhere (slept since then) that had it turned off despite you and I looking everywhere. 

tnx
Mike

In most all cases this will NOT be a problem but if for some reason you want to run the BBB offline or you do not have ntp access due to blocking or for any reason you could easily add a Real Time Clock to the BBB to achieve accurate time.

This clock works fine and it appears to be accurate at least at room temperature. I did no testing at temperature extremes. The method of doing this is still somewhat experimental and there probably will be changes as we go along on exactly how the clock is implemented in the code but for now this is a viable option for those who have a need to add it. Software support for this will be added to the next image release. Again I want to emphasize that having this clock is NOT a requirement for most all situations under which the BBB is used but you can certainly choose to experiment and try it out if you like.
