The only difference between these two dumps are the fact that the first
one isn't using the Sun convention for telling NFSv2 servers to set to
the current time (see the code in xdr_encode_current_server_time).

I don't see why this would be new behaviour after 2.6.21. The code for
this has been in the NFS client since 2.6.15 at least...
