Hasin Hayder has posted an example of a "world time search" he's worked up that uses the geonames.org and Yahoo! developer APIs to pin down the time at any given location.

I recently came by this site WorldTimeEngine where users can search the local time of any place using the name, street address or just latitude and longitude. Since that time I was thinking how easily you can make your own. As long there are some good people over there (For Geocoding API) - its a not a big deal, you know?

His script pulls the location of the place (latitude/longitude) from the Yahoo! geocoding API and passes that back into the geonames web service to get the local time. The result is an array with the lat/long, address you submitted and the time output in a standard string.

If you've ever wanted yout scripts to do something more "outside the box" and out in the real world, you might want to check out this new tutorial from NewsForge for a good start.

The concept's pretty simple - the form they build submits back to the page and writes the input out to a file. This file is then read by the controller for the LED they have connected and, with the proper input, will turn it on and off. The code for the PHP/web side of things is included, but it might take a little work to get the rest of the hardware interfaced (as the author saw as well).
