As a stubborn Swede (meaning most things goes wrong) this is at last an area where we are brilliant. yymmdd is since long standard in Sweden. Now since the Millenium festivitas yyyymmdd is getting more common also. But, alas, as *you* can't adopt to anything we have little or no use of any standards.
(yymmdd can be sorted by any application doing alphanumerical sorting btw.)
