Right way to get Web Server time and display it on Web Pages

codeigniter, javascript, php

Solution

Answering my own question

I found what I was looking for on Webdeveloper.com and it worked excellently for me.

serverDate.js

var xmlHttp;
function srvTime(){
    try {
        //FF, Opera, Safari, Chrome
        xmlHttp = new XMLHttpRequest();
    }
    catch (err1) {
        //IE
        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.open('HEAD',window.location.href.toString(),false);
    xmlHttp.setRequestHeader("Content-Type", "text/html");
    xmlHttp.send('');
    return xmlHttp.getResponseHeader("Date");
}

var st = srvTime();
var date = new Date(st);

html

<html>
  <head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <title>Server date/time</title>
    <script language="javascript" src="serverDate.js"></script>
  </head>
  <script language="javascript">
  var localTime = new Date();
  document.write("Local machine time is: " + localTime + "<br>");
  document.write("Server time is: " + date);
  </script>
  <body>
  </body>

Cheers!!

Problem

I am developing my website using `PHP Codeigniter Framework`. I want to display my webserver's time as well as client's machine time on some of my web pages. I successfully displayed client side time using `JavaScript` that updates the time every second by simply using `setInterval('clientMachineTime()',1000)` function. I want to display the web server time with the same working of my client side clock. I googled for this but could not find exactly what i am looking for. Any suggestion would be appreciated. Thanks.
