Hi mathieu_cupryk,
You just need to put one control inside the ascx page to display the clock time that mentioned in the article.
You can arrange the textbox - "clock" based on your preferred position.
Here is the attempt:

</script>
function updateClock ( )
{
  var currentTime = new Date ( );

  var currentHours = currentTime.getHours ( );
  var currentMinutes = currentTime.getMinutes ( );
  var currentSeconds = currentTime.getSeconds ( );

  // Pad the minutes and seconds with leading zeros, if required
  currentMinutes = ( currentMinutes < 10 ? "0" : "" ) + currentMinutes;
  currentSeconds = ( currentSeconds < 10 ? "0" : "" ) + currentSeconds;

  // Choose either "AM" or "PM" as appropriate
  var timeOfDay = ( currentHours < 12 ) ? "AM" : "PM";

  // Convert the hours component to 12-hour format if needed
  currentHours = ( currentHours > 12 ) ? currentHours - 12 : currentHours;

  // Convert an hours component of "0" to "12"
  currentHours = ( currentHours == 0 ) ? 12 : currentHours;

  // Compose the string for display
  var currentTimeString = currentHours + ":" + currentMinutes + ":" + currentSeconds + " " + timeOfDay;

  // Update the time display (Change the control name here)
  document.getElementById("clock").value = currentTimeString;
}

window.onload=function(){
      setInterval('updateClock()', 1000 );
}
</script>

<input type=text ID="clock" style="border:0"/>
      
<div id="loginbox">
....

Hi mathieu_cupryk,  
It's getting close. You need to assign the "ID" for the "clock" control instead of "Name" only. The object is being referred via document.getElementById().
eg:
 <input type="text" class="value" id="clock" name="clock" size="27" readonly="readonly" style="border: 0px;">
