Yes, I think that is the best solution.  It will of course be pretty
slow since rsync will have to read every file on the filesystem every
time, but without accurate mtimes I don't see at the moment what else
it could do.

If the problem only occurs in particular directories accessed by the
VMS machines then perhaps you can copy them using --checksum and leave
it off for the rest of the filesystem.
       
Perhaps you can hack something up involving your NFS server writing a
log of modified files, and then use that as a cue to rsync.

I think you will find using an rsyncd rather than copying between two
NFS filesystems should be much faster.

You can leave off --recursive --group --owner --perms because they're
implied by --archive, and --whole-file because it's implied by both
directories being local (including NFS).
