tDBAdvDateTimePicker and tAdvDateTimePicker have a scaling issue that affects usability. Of the time part, the final two digits are cutoff when the form is moved to a high-dpi display.
This forces me to use a time format of HH:mm:ss even though I really don't want the seconds, but otherwise the minutes part might become unreachable.
Also, specifying a time format like hh:mm:ss has the side effect that one cannot see if the time that was entered was meant to be AM or PM.
