datestyle problems?

Hi,

Have I missed something, or has some date behaviour
changed in going from 6.5.2 to 7.0.2?

drop table tdate;
create table tdate ( demo date );
set DateStyle to 'European';
insert into tdate (demo) values ('31-12-1999');
set DateStyle to 'US'; select demo as US from tdate;
set DateStyle to 'European'; select demo as European from tdate;
set DateStyle to 'SQL'; select demo as SQL from tdate;
set DateStyle to 'ISO'; select demo as ISO from tdate;
set DateStyle to 'German'; select demo as German from tdate;

Gives (with irrelevant lines deleted):
>        us
>   ------------
>    1999-12-31
Wrong? should be month day year;
>
>     european
>   ------------
>    1999-12-31
Wrong? should be day month year;
>
>       sql
>   ------------
>    31/12/1999
Wrong? should be month day year;
>
>       iso
>   ------------
>    1999-12-31
Right.
>
>      german
>   ------------
>    31.12.1999
Right.


Cheers,
