What about storing current geo coordinates and a timestamp of when they were recorded? I feel like that should be enough for a theoretical future system to adjust mapping for continental drift.

- ethbr1 3y agoThe problem with geo coordinates is reverse mapping them back into political owners, so you can then determine current timezone policy. There's 4 things at play here: - Coordinate location on the planet - Identifier for that location - Political entity for that location - Current timezone policy Of those, coordinates are the only thing that doesn't change over time (for the spans we're talking about). But are also a pain in the ass to use. F.ex. I'm sure someone on HN has the lat long for London memorized, but I don't.
- dmurray 3y agoLondon is perhaps the only major city where you could be expected to know one of these coordinates. It's defined to have longitude 0.
