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.
Answering my own question
I found what I was looking for on Webdeveloper.com and it worked excellently for me. I want to share it because it was not easy to find. I hope it will be helpful for others.
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!!
