"Some devices have geolocation, which could allow users to select from a geographically sorted list of time zones. A graphical selection interface can allow users to select from a map based on the timezone city coordinates in zone.tab. And packagers are of course always welcome to provide more sophisticated selection mechanisms on top of the minimimal facilities offered by tz. The user experience of enabling effective time zone selection by end users is already well outside the scope of the tz project."
Another possibility: if the device can access a server that will give UTC, then asking "What time is it where you are now?" will give an idea of the current offset, and you can present the zones that are near that offset.
