This means that you have a Date, Time or Timestamp field which contains data that is not valid for the field type eg :-
25:61 for a time
20093232 or 00000000 for a date
I suggest you take option D to get a dump and check the data in your Date, Time or Timestamp fields. If the program is reading the data from a file, you may need to update the data to contain correct values. Maybe someone has mis-typed a date or time or forgotten to fill it in. Your application should really have stopped the invalid data being entered in the first place.
Can you show us the code were the error occurs?
