I previously modified t5304 to make test-chmtime modify the mtime of
the file based on the system time rather than the file mtime precisely to
avoid this problem.  i.e. the argument to test-chmtime is now prefixed with '='

So I don't think it is related to out of sync clock on NFS server and client.
There may be a bug in the NFS client though.

Known by me, but I haven't mentioned it since I haven't had a moment to
diagnose it.

RHEL 5.2? me too.

RHEL 4.7 works fine, same NFS server (running 5.2).
