Another Way of Time Displaying in asp.net using javascript

<script type="text/javascript">

    function ShowTime() {

        var dt = new Date();

        document.getElementById("<%= TextBox1.ClientID %>").value = dt.toLocaleTimeString();

        window.setTimeout("ShowTime()", 1000);

    }  

</script>

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>

<script type="text/javascript">

    // a startup script to put everything in motion

    window.setTimeout("ShowTime()", 1000);

</script>
