that seems to make sense.  The advanced time on the 4 problems nodes looks to 
be the correct UTC time, but the others are using /local time/ in their logs, 
for some reason.  And localtime nodes are the ones NOT having problems.  
...??!

However, this looks to be more of a ROCKS / config problem than a general 
gluster problem at this point.  All the nodes have the md5-identical 
/etc/localtime, but they seem to be behaving differently as to the logging.

Thanks for the pointer.

Yes.
