I have a code which will tell you the time. It should hopefully work and should
change according to GMT daylight saving times It also tells you the date.
Here it is:

<p>
<script type="text/javascript">
<!--
document.write("Today's date is: " + Date());
// -->
</script>
</p>
<p>
<script type="text/javascript">

It should work. Good luck!
