Using JavaScript to display date and time

**geosite** · Jan 7, 2005, 22:51

I posted this on the PHP forum and was advised to seek a JavaScript solution.

If you look in the top right corner of my page at http://www.politix.us/world/eur/afg/index.php you'll see a PHP function that displays the date and time. This is the code behind it:

PHP Code:


<div id="pagedate"> (<em><?php echo date("l"); ?></em>) <?php echo date("F d, Y"); ?> <span id="pagetime"><?php echo date("h:i:s A"); ?></span></div>

I have two questions:

1. How can I make it dynamic, so that the minutes and seconds change even if a page isn't refreshed?

2. How can I make it display the VIEWER'S local time? It shows midnight when it's 9 p.m. my time, or something like that.

Also, would displaying seconds eat up a lot of bandwidth? If so, I might limit it to minutes.

Thanks.

Hi geosite, this is a quick example but should give you some ideas:

Code:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN">
<html>
<head>
<script type='text/javascript'>
window.onload = function()
{
  if (document.getElementById) {
    rtClock();
  }
}
var dayOfWeek = new Array('Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday');

function rtClock()
{
  var m = 'AM', now = new Date();
  setTimeout('rtClock()', 1000);
  var ele = document.getElementById('clock');
  var hours = now.getHours();
  if (hours == 0) hours = 12;
  else if (hours == 12) m = 'PM';
  else if (hours > 12) {
    hours -= 12;
    m = 'PM';
  }
  ele.innerHTML = dayOfWeek[now.getDay()] + ', ' +
                  hours + ':' +
                  now.getMinutes() + ':' +
                  now.getSeconds() + ' ' + m;
}
</script>
</head>
<body>


<div id='clock'></div>

</body>
</html>

Thanks for the tips. I may use PHP to display the date, since it's so much simpler, then use JavaScript to make a dynamic time display.
