Well, the detection isn't automated, but pulling down the new Olson db and building a new version of DT::TZ is.
For detection, I'm subscribed to the Olson db discussion list, where new versions are announced. When a new version is announced, I run a script to update DT::TZ, run the tests, and upload to CPAN. It's pretty straightforward.
