1. Timezone - we need to ensure all VMs have the same timezone (At least by default).

Best option would be to edit the deploy scripts and set the timezone to the host timezone?

should be fairly easy to add @TIMEZONE@ variable to the deploy script in a similar manner to what we do today in the domain XML.

It'll be in a command like 'ln -s /usr/share/zoneinfo/@TIMEZONE@ /etc/localtime

2. Time drifting - I have a feeling there's a time drift when we do all the freeze-thaw and snap/revert... Perhaps we should run 'ntpdate' after such actions?
