title: Limiting the hour range for UIDatePicker in UIDatePickerModeCountDownTimer mode?
body: <p>I'd like to limit the range of the hours shown in the UIDatePicker in UIDatePickerModeCountDownTimer mode from the current range of 0 - 23 to 0-6.</p>
  
  <p>Is this feasible or do I have to roll out my own UIPicker control?</p>
