No errors in the logs, to the RTC looks like the culprit. After fixing the 
RTC, I haven't experienced any more of the reboots. Bizarre... This box has 
run fine for years, then following the power outage, the RTC went nuts. I 
think that was simply the issue. However, I don't think we will ever explain 
why the RTC became an issue that caused the reboots. Looking at all the logs, 
the RTC has been all over the place this past month:

Oct 19 13:15:02 providence crond[955]: time disparity of 301 minutes detected
Oct 18 12:42:00 providence crond[958]: time disparity of -479 minutes detected
Oct 18 12:32:00 providence crond[1180]: time disparity of -479 minutes detected
Oct 18 11:19:01 providence crond[978]: time disparity of -479 minutes detected
Oct 18 09:44:01 providence crond[953]: time disparity of -478 minutes detected
Oct 12 09:24:01 providence crond[942]: time disparity of -79 minutes detected
Oct  7 10:55:59 providence crond[964]: time disparity of 253 minutes detected
Oct  5 07:55:57 providence crond[921]: time disparity of 383 minutes detected
Oct  3 16:23:01 providence crond[954]: time disparity of 301 minutes detected

300 is correct for the 5 hour offset for CDT, I can't explain the wild swings 
from Oct 3 to Oct 18. That is a 862 minute difference between Oct 5 and Oct 
18. init scripts? kernels?

The other box that experienced this problem had the following:

Oct  5 08:27:32 localhost crond[789]: time disparity of -546 minutes detected
Sep 27 22:18:01 localhost crond[794]: time disparity of -475 minutes detected

both those dates must have been kernel updates, because that is the only time 
that box gets restarted. Strange, thanks for your help.
