Darrell,
In our next release we replaced Microsoft DatePicker with a Custom DateTimePicker control which is used inside FeatureDataForm and FeatureDataGrid. You will be able to also set custom date time string formats 'MM/dd/yyyyy hh:mm:ss' and indicate whether you want dates to show as UTC or Local time. Default is Local time. By default Date and Time will be displayed in the DateTimePicker but if you don't want to see time you can always remove it by using a custom date time format string that doesn't include time i.e. 'MM/dd/yyyy'. DateTimePicker also will diaplay date formats based on CurrentUICulture.
