I tried the following code, it didn't give any output


<html>
<title>Untitled Document</title>
<head>



<script type="text/javascript">
var ajaxRequest;


function getServerTime(){

ajaxRequest=getXMLHttpRequest();
if((!ajaxRequest){

	document.getElementById("showtime").innerHTML="Request error";
	return;
}
var myURL="telltime.php";
var myRand=parseInt(Math.random()*999999999);
myURL=myURL+"?rand="+myRand;
ajaxRequest.onreadystatechange=ajaxResponse;
ajaxRequest.open("GET",myURL);
ajaxRequest.send(null);
}	

function getXMLHttpRequest(){
var xmlHttp,e;
try
  {
  // Firefox, Opera 8.0+, Safari
  xmlHttp=new XMLHttpRequest();
  }
catch (e)
  {
  // Internet Explorer
  try
    {
    xmlHttp=new ActiveXObject("MSXML2.XMLHttp.6.0");
    }
  catch (e)
    {
    try
      {
      xmlHttp=new ActiveXObject("MSXML2.XMLHttp.3.0");
      }
    catch (e)
      {
      alert("Your browser does not support AJAX!");
      return false;
      }
    }
  }
  return xmlHttp;
  }

function ajaxResponse(){
if(ajaxRequest.readyState!=4){return;}
else{
	if(ajaxRequest.status==200){
	document.getElementById("showtime").innerHTML=ajaxRequest.responseText;
}
else{
	alert("Request Failed");
}
}

function getServerTime(){

   ajaxRequest=getXMLHttpRequest();
   if((!ajaxRequest){

You have an extra ( in your if statement, it should read: if(!ajaxRequest){

Other than that it worked for me. Also in your telltime.php, you do not need the HTML in there, only the <?php echo date('H:i:s'); ?>. I only say this because you are returning extra information to your function that is unnecessary and will mess with formatting later.

Tips for debugging your code: Use Firefox. Look in Firefox's Error Console (Tools->Error Console). It helps a lot. Gl.
