Calendar Control - Incorrect Date Format

Hi ,

I have the below CalendarExtender control associated with the Textbox on the ASPX page.

<asp:CalendarExtender ID="TextBox16_CalendarExtender" runat="server"
                        Enabled="True" TargetControlID="TextBox16" TodaysDateFormat="dd/MM/yyyy HH:MM:ss" Format="dd/MM/yyyy HH:MM:ss"></asp:CalendarExtender>

But despite of specifying the dateformat in the control, it's bringing the date in MM/DD/YY HH:MM:ss format instead of dd/MM/yyyy HH:MM:ss format.

How can I change this default behaviour?
