As the name suggests, really only works in WebKit. I initially tried it in my current browser of choice, the latest Opera, and sure enough doesn't render properly. Tried it in Chrome and looks great. Good job.
Really bad on Firefox, too, but that is indeed to be expected. It'd be nice to have a non-WebKit-only version eventually, perhaps, to challenge http://everytimezone.com.
I'm very sad that I dont understand how the globe is being drawn.
Teach me please
looks great. The jet was a really nice touch. Had to <ctrl-f> to find the city I was looking for, consider alphabetizing? You did? Oh and you thought it would better to group them by region? I can see how that would make exploring the time zones more interesting, but I was looking for a city when I landed at your site :) sortby(region|name). What's that? You think that would clutter the interface; I suppose you're right, it is pretty slick the way it is.
