This seems like a slightly odd place in the code to address the problem.
The xenconsoled daemon has the ability to save all guest data to a logfile
in /var/log/xen/console/guest-$NAME.log. So if you want to save logs and
timestamp them, it'd seem more natural to put timestamping capability in
the xenconsoled program.
Of course this only handles paravirt console. For fullvirt guests, if you
wanted to timestamp the serial console output, then something would need
to be done with QEMU - or perhaps get QEMU to feed the serial data to the
xenconsoled program for logging to disk ?
