Getting a sharepoint page to refresh automatically

Enabling your SharePoint page to refresh automatically after x seconds is as simple as adding a Content Editor web part and adding the following javascript to it in the source editor:

<script type="text/javascript" language="javascript">
var reloadTimer = null;
var sURL = unescape(window.location.pathname);

function setReloadTime(secs)
{ if (arguments.length == 1)
   { if (reloadTimer) clearTimeout(reloadTimer);
       reloadTimer = setTimeout("setReloadTime()", Math.ceil(parseFloat(secs)*1000));
   }
   else
   { reloadTimer = null;
     location.reload(true);
     window.location.replace( sURL );
   }
}

setReloadTime(30);
</script>
