    Lightbulb Getting server date/time with no server side script


    I'd been looking for some way to get server date/time without using any server side script (such as ASP, PHP, etc).

    I found this and it worked just excellent for me! I just want to share it because it wasn't easy to find.

    I created a js document with code:

    var xmlHttp;
    function srvTime(){
    	try {
    		//FF, Opera, Safari, Chrome
    		xmlHttp = new XMLHttpRequest();
    	catch (err1) {
    		try {
    			xmlHttp = new ActiveXObject('Msxml2.XMLHTTP');
    		catch (err2) {
    			try {
    				xmlHttp = new ActiveXObject('Microsoft.XMLHTTP');
    			catch (eerr3) {
    				//AJAX not supported, use CPU time.
    				alert("AJAX not supported");
    	xmlHttp.setRequestHeader("Content-Type", "text/html");
    	return xmlHttp.getResponseHeader("Date");
    var st = srvTime();
    var date = new Date(st);
    Now, I can use this js within a html like this:

    HTML Code:
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <title>Server date/time</title>
    <script language="javascript" src="serverDate.js"></script>
    <script language="javascript">
    var localTime = new Date();
    document.write("Local machine time is: " + localTime + "<br>");
    document.write("Server time is: " + date);
    You may change your machine date/time and check both dates.
