var finishedtext = "Countdown finished!";
var end;
if(localStorage.getItem("end")) {
    end = new Date(localStorage.getItem("end"));
} else {
    end = new Date();
    end.setMinutes(end.getMinutes()+minutesleft);
    end.setSeconds(end.getSeconds()+secondsleft);
}
var counter = function () {
    var now = new Date();
    var diff = end - now;
    diff = new Date(diff);
    var sec = diff.getSeconds();
    var min = diff.getMinutes();
    if (min < 10) {
        min = "0" + min;
    }
    if (sec < 10) {
        sec = "0" + sec;
    }    
    if(now >= end) {    
        clearTimeout(interval);
        localStorage.setItem("end", null)
        document.getElementById('divCounter').innerHTML = finishedtext;
    } else {
        var value = min + ":" + sec;
        localStorage.setItem("end", end);
        document.getElementById('divCounter').innerHTML = value;
    }
}
var interval = setInterval(counter, 1000);
</script>

Another example    for timer but it will reset when you  reload your page ..

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <script language ="javascript" >
        var tim;
     
        var min = 20;
        var sec = 60;
        var f = new Date();
        function f1() {
            f2();
            document.getElementById("starttime").innerHTML = "Your started your Exam at " + f.getHours() + ":" + f.getMinutes();
           
       
        }
        function f2() {
            if (parseInt(sec) > 0) {
                sec = parseInt(sec) - 1;
                document.getElementById("showtime").innerHTML = "Your Left Time  is :"+min+" Minutes ," + sec+" Seconds";
                tim = setTimeout("f2()", 1000);
            }
            else {
                if (parseInt(sec) == 0) {
                    min = parseInt(min) - 1;
                    if (parseInt(min) == 0) {
                        clearTimeout(tim);
                        location.href = "default5.aspx";
                    }
                    else {
                        sec = 60;
                        document.getElementById("showtime").innerHTML = "Your Left Time  is :" + min + " Minutes ," + sec + " Seconds";
                        tim = setTimeout("f2()", 1000);
                    }
                }
             
            }
        }
    </script>
</head>
<body onload="f1()" >
    <form id="form1" runat="server">
    <div>
      <table width="100%" align="center">
        <tr>
          <td colspan="2">
            <h2>This is head part for showing timer and all other details</h2>
          </td>
        </tr>
        <tr>
          <td>
            <div id="starttime"></div><br />
            <div id="endtime"></div><br />
            <div id="showtime"></div>
          </td>
        </tr>
        <tr>
          <td>
           
              <br />

How to handle XML with PHP

What is XML? The  eXtensible Markup Language  is a way to structure your data for sharing across sites. Some of the technologies that are crucial to the web like  RSS  (Real Simple Syndication) and  Podcasts  are special flavors of XML. The beautiful thing about XML is that you can easily roll your own for anything you need. XML is easy to create because it’s a lot like HTML…except you can make up your own tags. Let’s say, for example that you’re putting together a feed for a list of songs playing at your own radio station.

We make up a couple of tags called  <title>  and  <artist>  and wrap each of them around a  <song>  tag. We’ll create a dateplayed attribute for each song with the date and time the song was played.

Need for XSL In case of HTML document, tags are predefined such as table, div, and span; and the browser knows how to add style to them and display those using CSS styles. But in case of XML documents, tags are not predefined. In order to understand and style an XML document, World Wide Web Consortium (W3C) developed XSL which can act as XML based Stylesheet Language.
