You have put me on the right track here.  I looked at those files and discovered that they are all dated Dec 27, 1903 on my computer, and Feb 7, 2040 on the fileserver.

Interesting.  I guess the source archive that I copied those pdf's from must have had something funky going on with the file dates.

I just used the touch command to set the dates to something sane, and I suspect that will solve the problem.  It appears that rsync have been looking at 1903 vs 2040 and saw that the dates differ, but couldn't set them to match for whatever reason.
