Since we all live in the same place, you will end up with multiple zones for the same region depending upon who you count as important. The same would be the case then for the Apache in southern CO, the ethnic Uyghurs in China, etc… If your app is about charting airline arrival and departure times, then using an Amish schedule would be foolish. They use horses for transportation anyway. In my own software, I just add a TMessage (a string list) which takes the julian date as a parameter to warn users about these exceptions. Unfortunately it is far from being all encompassing, but as the user sees enough of these messages through use, it helps to generate the appropriate amount of caution.
