  • It's unclear if you are asking how to do this without JS or if you want to know why this code isn't working (in which case the error message in the content should be a big clue). What element are you trying to get by its ID? – Quentin Commented Sep 9, 2019 at 16:08
  • It also appears, that document.lastModified returns only the current date and time when retrieved on a web page. – Teemu Commented Sep 9, 2019 at 16:13
  • Your html is not well formed, so your question is really weird. – iguypouf Commented Sep 9, 2019 at 16:13

Reset to default 4

You can use the date object and then use ISOString method,the use substr to get the time from the string

function myFunction() {
  var x = document.lastModified;
  document.getElementById("demo").innerHTML = new Date(document.lastModified).toISOString().substr(11, 8);
}

myFunction()
This is last updated time <span id='demo'></span>

First you have 2 bodys, dont want that.. then you just need to add the #demo element to select and innerHTML the lastModified value.

<!DOCTYPE html>
<html>

<body onload="myFunction()">
  This is last updated time <span id="demo"></span>
  
  <script>
    function myFunction() {
      var x = document.lastModified;
      document.getElementById("demo").innerHTML = x;
    }
  </script>
</body>

</html>

As Requested, All you needed was a div element with id "demo"

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Document</title>
    <script>
        function loadTime() {
            document.getElementById("demo").innerHTML = document.lastModified;
        }
    </script>
</head>
<body onload="loadTime();">
    <div id="demo"></div>
</body>
</html>
