I've noticed that the World Clock function of the Clock App does not really highlight the correct time zones on the world when specific City/Zones are selected.
As you can see from the screenshot Paris (France) is selected, but the highlighted zone is UTC+2, which reflects the time, but not the geography. Similarly, the Delhi entry highlights (about) UTC+3, considerably west of India on the map.
Now that it is winter, my home location of Sydney does highlight the east coast of Australia, but during summer, it highlighted UTC+11, which again reflected the time, but not geography.
Highlighting the wrong geographical bands looks really odd in this application.
