NFS is known to be non-POSIX-compliant.  It is probably some clock skew 
affecting things, but I haven't had a chance to actually play with that 
particular system to see if I can come up with a workaround (some way to 
force the timestamp comparisons to take place only between timestamps 
generated on the server, or generated on the client, but not mixed 
between the two).
