So much ado about so little things.

As Andreas and Thomas told you before (in the german NG):
don't apply DateParams as String.

IB_Query1.ParamByName('Datum').AsString :=
DateToStr(DateTimePicker1.Date);

The problem ist that you store dates in Timestamp fields.
Either store them as DATE (in dialect 3) or make sure that you cut the
timestamp field before saving (sth. like trunc ( ....) in the Before
Post)

Then you can assign the param like:
IB_Query1.ParamByName('Datum').AsDateTime :=
trunc(DateTimePicker1.Date);

and all your problems are gone.
