Done. Apologies for the delay in getting to this, I've been totally
swamped with other stuff. New version of xorriso built and installed
on pettersson (the CD build machine) with

#define Xorriso_timestamP "2014.04.08.180000"

Please shout if you want me to change to another newer version, e.g. for the
hppa changes that you've been talking about elsewhere.

Other folks: could you please test the output of the next daily builds
and verify these work better for you?
