Displaying Server Date and Time continuously in Web Applications is a big deal. It is difficult in java script to calculate the date and time and may consume memory in IE.
I have done it two ways one using Web Services and other using Iframe.
At last satisfied with the Iframe implementation.
I used some DHTML and Javascript to display the Server Date and Time along with Server side code.
The advantage of this script is the page is displayed only when the page loads other wise it will not display any thing and there is no flickering in page.
ServerDateTimeTest.htm
===========================
<body>
<!--<span id="clock" nowrap></span>-->
<iframe name="FRAME1" src='serverDateTime.aspx' width="350" height="20" frameborder="0" style="visibility:hidden" >
</iframe>
</body>
ServerDateTime.aspx
===========================
<script language="javascript">
function PageInit()
{
VisibleIframe(true)
setInterval("ReloadPage()", 1000 * 60);
}
function ReloadPage()
{
VisibleIframe(false)
location.reload();
}
function VisibleIframe(Visible)
{
var strdisplay = "hidden";
if(Visible)
{
strdisplay = "visible";
}
if(window.parent != null && window.parent.document.getElementById("Frame1") != null)
{
window.parent.document.getElementById("Frame1").style.visibility = strdisplay;
}
}
</script>

For Performance improvement Cache the page for one minute.
