The TimePicker control supports selecting a time of day from a list of times. Use the ItemsSource property to specify the list, and the SelectedTime property to retrieve the selection.
To have the control automatically generate the list of times, specify the MinTime, MaxTime and SuggestedTimeInterval properties.
The TimeSpanPicker control supports selecting a TimeSpan (duration) from a list. The control formats TimeSpans as readable English rather than just a hours:minutes presentation. Again, use the ItemsSource property to specify the list, and the SelectedTimeSpan property to retrieve the selection.
The time controls support up-down functionality: the user can increase and decrease the selection using the up and down arrow keys. The amount is controlled by the Change property. The controls optionally offer buttons for increasing or decreasing the selection, the visibility of which is controlled by the IsUpDownVisible property.
