I think 17.11.1858 is the date Firebird uses when storing 0 in a date field. Not sure whether this is of any help to you or not, but check that you do not skip assigning to some records or try to assign an empty date (NULL) to them (you can assign NULL e.g. by calling TIB_Query1.FieldByName('WhateverMyFieldIsCalled').Clear;, I'm uncertain what happens if you try TIB_Query1.FieldByName('WhateverMyFieldIsCalled').AsDateTime:=NIL; or similar or if you use a TIBOTable/TIBOQuery).

HTH,
