title: Extended Toolkit WPF DateTimePicker Seconds precision
body: <p>I am using the WPF Extended Toolkit's DateTimePicker. However, when I open the calendar to pick a date, it is only possible to spin hour and minutes. The seconds can only be changed when the calendar is closed.</p>
  
  <p>I would like to add seconds to the time shown below the calendar when picking a date, in a way it is consistent with the time shown below.</p>
