Non-interactive method for dpkg-reconfigure tzdata

When I first setup an Ubuntu server, I make sure I `aptitude install tzdata`, then `dpkg-reconfigure tzdata` so that I set my timezone properly. I am trying to automate my server setup with a script, and noticed this piece sort of throws a wrench into it being automatic, as it requires an interactive session with user intervention. Is there a way to use dpkg-reconfigure without it being interactive?
