Hovering over each place on the map, you have to physically select the item to see what it would be. There should be a tooltip appearing while hovering over each possible selection.
The original idea was to attach a tooltip to the dot on the map when you hovered near it. This is unworkable because the dots are simply drawn on a GnomeCanvas and therefore I don't believe I can attach a tooltip. Ideas?

I remember a previous version of the installer (maybe with Fedora Core 3 ?) used to have the select box change automatically to the correct timezone when the mouse hovered on or near a dot on the map.
The timezone screen has been reworked to take care of this issue.
