klockan ska gå efter servern

Här är min klocka som kommer från jojoxx.net:

<span id=klocka style="position: absolute;">        </span><br>
<script language="JavaScript">
var elementId = "klocka";
function clock(){
	if (document.layers || document.all || document.getElementById){
		now = new Date();
		h = "0" + now.getHours();
		h = h.substring(h.length-2, h.length);
		min = "0" + now.getMinutes();
		min = min.substring(min.length-2, min.length);
		sec = "0" + now.getSeconds();
		sec = sec.substring(sec.length-2, sec.length);
		time = " " + h + ":" + min + ":" + sec;
		if(document.layers){
			with (document[elementId].document){
				open();
				write(time);
				close();
			}
		} else if (document.all){
			document.all[elementId].innerHTML = time;
		} else if (document.getElementById){
			jxdocrange = document.createRange();
			jxdocrange.setStartBefore(document.getElementById(elementId));
			while (document.getElementById(elementId).hasChildNodes()){
				document.getElementById(elementId).removeChild(document.getElementById(elementId).lastChild);
			}
			document.getElementById(elementId).appendChild(jxdocrange.createContextualFragment(time));
		}
		setTimeout("clock()", 1000);
	}
}
setTimeout("clock()", 1000);
</script>

Denna klocka går efter datorns klocka men jag vill att den ska gå efter serverns klocka. Hur fixar man det?

Det klarar du inte med enbart clientside JavaScript. Har du tillgång till något serverside-script? Via cgi eller asp kanske?

ASP kan jag använda på servern.

Hmm.

Jag tänkte nog lite fel. Återkommer

Ingen som vet hur man kan göra?

<span id=klocka style="position: absolute;"></span><br>
<script language="JavaScript">
var elementId = "klocka";
var serverdate=new Date(<%=year(Now)%>,<%=month(Now)-1%>,<%=day(Now)%>,<%=hour(Now)%>,<%=minute(Now)%>,<%=second(Now)%>);
var clientdate=new Date();
var difftime=serverdate-clientdate;
function clock(){
	if (document.layers || document.all || document.getElementById){
		now = new Date(); now = new Date((now-0)+difftime);
		h = "0" + now.getHours();
		h = h.substring(h.length-2, h.length);
		min = "0" + now.getMinutes();
		min = min.substring(min.length-2, min.length);
		sec = "0" + now.getSeconds();
		sec = sec.substring(sec.length-2, sec.length);
		time = " " + h + ":" + min + ":" + sec;
		if(document.layers){
			with (document[elementId].document){
				open();
				write(time);
				close();
			}
		} else if (document.all){
			document.all[elementId].innerHTML = time;
		} else if (document.getElementById){
			jxdocrange = document.createRange();
			jxdocrange.setStartBefore(document.getElementById(elementId));
			while (document.getElementById(elementId).hasChildNodes()){
				document.getElementById(elementId).removeChild(document.getElementById(elementId).lastChild);
			}
			document.getElementById(elementId).appendChild(jxdocrange.createContextualFragment(time));
		}
		setTimeout("clock()", 1000);
	}
}
setTimeout("clock()", 1000);
</script>

Tack så mycket, det funkar!
