Have a look at the Block Refresh module ( http://drupal.org/project/block_refresh). You can set a number of seconds after what a block should refresh automatically.

I have a block that contains javascript which calls a website that sends an ad to this block (see below: Note: I changed the domain name to adserveringwebsite). How can I add code that will call the below javascript every minute so that a different ad will show up every minute instead of just one ad at page load?
<SCRIPT type="text/javascript" LANGUAGE="javascript" src="http://www.qksz.net/1e-kn60"> </SCRIPT>

Thanks,
