AFAIK, by default the appliances will use UTC time/date and will get the time from the main Ubuntu time server.
You can update the time zone by followiung this blog post.
Generally the Ubuntu time server should be fine, but if you want to change it then that can be done via editing /etc/ntp.conf (look for the line that says 'server ntp.ubuntu.com' and change that). ALthough I think if you use the Webmin method you can adjust that from within Webmin itself? Let me know if you can't and I'll have a look.
The timezone needs to be set
