jQuery(document).ready(function() {
    var foo = jQuery('#foo');
  
    function updateTime() {
        var now = new Date();
        foo.val(now.toString());        
    }
  
    updateTime();
    setInterval(updateTime, 1000); // 5 * 1000 miliseconds

    let minutes = now.getMinutes()
    // Get seconds

    // Get the month in number and use it to get a textual month
    let month = months[now.getMonth()]
    // Get the date
    let date = now.getDate()
    // Get full year
    let year = now.getFullYear()
    // If min/sec/hour are smaller than 10, add '0' to keep consistency
    if (minutes < 10) {
      minutes = '0' + minutes
    }
    if (seconds < 10) {
      seconds = '0' + seconds

    // Merge all of the above in a string

    // Update the value with string
    foo.val(time);

Using moment:

jQuery(document).ready(function() {
    var foo = jQuery('#foo');
    
    function updateTime() {
        var now = moment().format("hh:mm:ss ddd MMM DD YYYY");
        foo.val(now);        
    }
  
    updateTime();
    setInterval(updateTime, 1000);
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.29.1/moment.min.js"></script>
<input id="foo" name="foo" type="text" value="" size="55" />

You can separate out the time and date element, then join the time/date back.

jQuery(document).ready(function() {
    var foo = jQuery('#foo');
  
    function updateTime() {
        var now = new Date();
        var timeTmp = now.toLocaleTimeString(); 
        var dateTmp = now.toDateString();
        foo.val(timeTmp + " " + dateTmp);        
    }
  
    updateTime();
    setInterval(updateTime, 1000); // 5 * 1000 miliseconds
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input id="foo" name="foo" type="text" value="" size="55" />

Please avoid using moment.js as it increases page load time. You can use day.js instead. It is a Fast 2kB alternative to Moment.js with the same modern API.

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="https://unpkg.com/dayjs@1.8.21/dayjs.min.js"></script>

<script>
$(function() {
  var foo = jQuery('#foo');

  function updateTime() {
    var now = dayjs().format("hh:mm:ss ddd MMM DD YYYY");
    foo.val(now);
  }

  updateTime();
  setInterval(updateTime, 1000);
});
</script>

<input id="foo" name="foo" type="text" value="" size="55" />
