thecolor

I've looked a bit over the forum for a similar function.  Unfortunately I'm not so strong at PHP (basics)... and am trying to make a table background color change based on the time of day. Like the iGoogle background that changes based on your zip code for weather and such,  I'd like to be able to capture the time the user visiting is in (wherever in the world) and display a background color related to the time of day.  (i.e. black for darkness and yellow for noon or similar.). Any help would be greatly appreciated. Thanks, ~TC
