seeking time zone maps, free non-licenced

I'm building a beautiful time zone selector, as a jQuery UI widget.

What I need is a layered PSD file where the bottom layer is a simple mercator world map, and each layer above it is a shape covering the geography affected by each time zone.

I've seen UI components like it, for example the Date & Time preferences in Mac iOS Lion. In fact what I'm building is inspired by that one, but it will be slightly awesomer.

The goal is to lay the map on the page, then as you interact with the UI will highlight the map using a sprited overlay.

I'll resize the images into multiple sizes, so a high-rez original would be awesome.

Sounds simple. But so far I've had trouble finding good source images.

I do have a very-high resolution black and white image with outlines of the time zones. As a last resort, I might end up tracing that in PhotoShop... it'll take hours I'm sure. drat I was hoping this would be a quick little project done in an afternoon

Have you checked out Nasa or CIA websites? Maps galore, all free to use.

Have you got all the DST issues nailed? I see millions of sites with clocks that appear to be an hour off for half of the year.

Time Zones are some of the most complex things to program.

oh lucy24 I just mean a simple green-and-blue world map that fits in a rectangle. I don't care if it's Mercator or some other projection.

btw, [xkcd.com...]

what would be better than a flat map would be a rendered 3d globe with the time zone area extruded, yadda yadda.

I just want to get this done and move on... Besides looking for map images, I haven't started yet and it's sitting on my TODO pile taunting me

I bet you thought tangor was kidding about the cia. But they're a great information source. When, ahem, they choose to be.

Watch out for Nepal. It's even weirder than India and Newfoundland.
