Daan> That’s a nice way of obscuring the dropdown, but in the end it’s the same method. Both ways require some geographical knowledge about the country the event is in. Most timezone names are actually pretty identifiable if you known a bit about the location. Take for example the name of our timezone—Europe/Amsterdam—not that hard to figure out if you know that Amsterdam is located in the Netherlands. Providing a map not only requires geographical knowledge of the user but there’s also the issue of creating these maps and clickable regions :-(
On another note, I actually was wrong about the assumption that US states have a single timezone, there are several states that have multiple timezones. Australia is a bit easier, their state boundaries are also timezone boundaries.
Well, I’ll just keep working on this… sooner or later I’ll get something done.
