This is because there are only two time formats, 24-hour or 12-hour.  
So we *can* use the user's preference here, because the freely entered  
time is distinguishable. Dates based on user preferences are not.

Yes, and I've seen your reply. I had refered to him, because having  
set individual preference values is the only reason why default values  
(or hooks) won't be used.
