/* FIX ME>>>>>
* notes on sync weirdness.
*
* This class grew out of a system which used external RTC that had to share
* a buss with all sorts of sensors.
*
* Rather than hog the buss a running seconds count was maintained (unixtime)
* and the time variables were updated and the rtc referenced once a minute.
*
* With an internal rtc this gets a little krufty.
*
* On the other hand a less than perfect clock can be implimented on systems
* w/o access to RTCs by counting seconds using whatever millis is using.
*
* this is not currently implimented but we will leave the cruft so it can be.
