Example

In this example, we will set the seconds field of the current time to 01 through setUTCSeconds(): 

<script type="text/javascript">

var d = new Date()
d.setUTCSeconds(1)
document.write(d)

</script>

Output:

If the specified argument is outside the expected range, calling setUTCSeconds attempts to update the latest information for the Date object accordingly. For example, if secondsValue uses 100, the minutes stored in the date object will be incremented by 1, and 40 will be used for seconds.

Example:

<html>
<head>
<title>JavaScript setUTCSeconds Method</title>
</head>
<body>
<script type="text/javascript">
  var dt = new Date( "Aug 28, 2008 13:30:00" );
  dt.setUTCSeconds( 65 );
  document.write( dt ); 
</script>
</body>
</html>

This will produce the following results:

Thu Aug 28 13:31:05 UTC+0530 2008
