--- Comment #4 from François Gouget fgouget@codeweavers.com --- Could it have nothing to do with RTL at all and just be different date/time conventions like in English (en_US) the date format is mm/jj/aaa but in French (at least fr_FR) it's jj/mm/aaaa? Note sure why it would be specific to v6 though. Maybe older versions did not always take the date/time convention into account?
