HELP!!! JavaScript (Clock)

[his boy elroy]

I am creating a new website for my small business. There is a page on the site that contains a map of the world I created. I have made 24 seperate images (simulate the earth rotation) that I would like synchronized to change every hour. In effect it acts as a timezone clock. you can view a static example on my site > http://edesedoret.com/company.html

What I need is a script that will update the image with a new one sequentually (example: EST_01, EST_02, ect) every hour. I will upload this to my internet providers server so I don't know if it will be sequenced with the servers clock or the one from my computer prior to the page being uploaded. Is there Javascript that exsist that I can use? I saw a site with a similar feature and I copied part of the code:

<!-- use hour to select map image -->

<td valign="top" width="445"> <img src="/company/graphics/timezone_images/GMT_20.gif" width="471" height="253" border="0" alt="world map" usemap="#Map"></td>
