It's weird that this just got to the home page of hacker news too: http://news.ycombinator.com/item?id=2544198. I've never heard about 'logical' puctuation before and today I've seen it twice in HN alone....
It could have easily been a lot worse. It's a quirk of geography that the part of the world exactly 180 degrees from London, which just happened to be the capital of the world when the human race got around to setting up sensible time zones, happens to be a north-so-south slice of mostly unpopulated ocean, where only a few minor islands need to worry about this kind of thing.
Heck, there are a lot of possible globes where there's no sensible place to put an international date line at all... every north-south slice goes through a populated landmass.
And some of those are just our globe, rotated. (I'd give an example, but it's hard to come up with one because I don't have an actual globe that I can play around with.)
Put a pole bang in the middle of the largest landmass, Eurasia-Africa, and every line of longitude will cut through some temperate-zone habitable land.
I'm doing the same thing for my iPhone app. Thanks for sharing this. I was thinking about a way to share mine but only partially. I have a column for comments, for example that I might not want to expose.
But I don't think that's what he wants... I believe this is a web app, am I right?
