Setting the Timezone with an automated script
You should be able to do this with
cp /usr/share/zoneinfo/America/Los_Angeles /etc/localtime
Substitute the appropriate timezone in the above command.
On Ubuntu 12.04 the following did the trick for me:
# http://manpages.ubuntu.com/manpages/precise/man7/debconf.7.html
export DEBCONF_NONINTERACTIVE_SEEN=true DEBIAN_FRONTEND=noninteractive
echo "Europe/Berlin" > /etc/timezone
dpkg-reconfigure tzdata
Try this:
echo "Europe/London" > /etc/timezone
dpkg-reconfigure -f noninteractive tzdata
