My goodness, I didn't realize how many states are dual time zone. Florida, Oregon, Idaho, both of the Dakotas, and many more - I assume there's a historical reason for each, but that has got to play havoc with things at the state administrative level.
And look at Michigan - given the odd spatial realities of the state, that's just bloody minded. I didn't realize Arizona was that county-by-county nuanced: I assumed the whole state did its own "screw clock changes" thing (tho the oddity of Wendover, a recent change, makes sense). And Puerto Rico looks to be doing Eastern time merely out of politeness.
