Import organization accounts does not update date field

Import organization accounts does not update date field

Hi

I'm trying to import an XLS or CSV file to update my datas. I have a monetary field and a date field.

Ex : "TOTO","298.5","2011-09-30"

Monetary field is ok. Date field won't update. I've tried to convert date to yyyy-mm-dd , dd/mm/yyyy ... nothing works.

I need some help at this point please :)

Regards
