How can I set a Datetimepicker control or MothCalendar to use a different Calendar or Culture?

From http://support.microsoft.com/default.aspx?scid=kb;en-us;889834:
The DateTimePicker and MonthCalendar control do not reflect the CurrentUICulture property of an application's main execution thread when you created a localized application in the .NET Framework, in Visual Studio 2005, or in Visual Studio .NET
