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.
