Problem with Date and Interbase 5.5 ODBC driver

When I use MyQuery.ParamByName('a name').AsDate := Now and I use
ExecSQL the system reply that :
[INTERSOLV][ODBC Interbase driver] Timestamp parameters with zero
scale must have a precision of 13, 16 or 19. Prameter
numer :1, precision: 0.

When I take a look with BDE Explorer I see that there is ???? for the
field date in each table. Time is a godd value : 00:00:00

When I can change the settings for the date ? I have found nothing in
ODBC Driver setup, BDE...
