Process-1 (Using C# in ASP.Net Page):
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:Timer ID="Timer1" runat="server" Interval="100" ontick="Timer1_Tick"> </asp:Timer>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<table style="height:30px; width: 100%; font-size: small;">
<tr>
<td bgcolor="#40541C"
style= "color: #FFFFFF; text-align: right; width: 250px;">
<asp:Label ID="lblTimer" runat="server"></asp:Label>
</td>
</tr>
</table>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Timer1" EventName="Tick"></asp:AsyncPostBackTrigger>

</asp:UpdatePanel>
protected void Timer1_Tick(object sender, EventArgs e)
{
lblTimer.Text = "Date Time: " + DateTime.Now.ToString("dd.MM.yyyy, hh:mm:ss tt");
}
Process-2 (Using JavaScript):
<script type="text/javascript">
function ShowCurrentTime() {
var dt = new Date();
//var date =
document.getElementById("lblTime").innerHTML = dt.toDateString() + ', ' + dt.toLocaleTimeString();
window.setTimeout("ShowCurrentTime()", 1000); // Here 1000(milliseconds) means one 1 Sec
}
</script>
<body onload="ShowCurrentTime()"> </body>
