Added Time - can only date be shown in view

Added Time - can only date be shown in view

I like added time field to use for filtering, but would only like to see the date, not the time i.e.:

4/03/2009
not 4/03/2009 21:45:46

I cannot find where I can set this field (it seems to be a hidden field). Any help would be appreciated.
Keep up the good work - this product is amazing!!!
