Care to elaborate?
- Crespyl 10y agoI don't know of any parcels of land that are simultaneously in more than one zone, but I do know that (until recently?) Indiana used to change time zones from Eastern to Central instead of using DST.
- 77pt77 10y agoI knew that. What I understood was same geographical location with several time-zones at an instant in time. Modulo border disputes I don't know of any such thing.
- jaggederest 10y agoThere are several places on earth that have an official and unofficial time zone, chiefly on time zone borders - some places in Indiana, for example, and the far western part of China where the time zone varies from solar time very significantly. In those places, if you ask a user where they are, and then show them a time zone based on that, it may not reflect what they think.
- kedean 10y agoNot sure if it's what they meant, but the boundaries move, so the timezone you store in a location today may not be the one that it corresponds with in a year. https://en.wikipedia.org/wiki/Time_in_Indiana https://en.wikipedia.org/wiki/Time_in_Indiana
