Key control of the time control

Question

What I really like about the time control that it is so easy to set
using the arrow keys on my keyboard. Unfortunately this doesn't seem to
work with the minutes and seconds. Anyone have an explanation for this?

I learned some more: as you all know a "value change" event in most
controls fires after editing when pressing enter or clicking outside of
the control. The same is the case when typing inside the time control.
But using the arrow keys in the time control is another animal: every
key press fires a "value change" event. This explaines some of the odd
behaviour: when you manually enter a value, the control is in edit
mode. The entered value will only stick when you invoke the "value
change" event. Because the edit mode the arrow key value change event
cannot operate. Why it cannot operate in all "lower" fields is strange
to me. Since every field can be changed independently inside one
control, every field can invoke the value change event invoked by the
arrow keys. When invoked in a "higher" field, it will override the edit
mode in a lower field. After all, you cannot edit multiple fields at
once.
