I return to http://www.unicode.org/mail-arch/unicode-ml/y2011-m10/att-0059/1999-12-31.html
Microsoft programs (Internet Explorer, MS Word), display this as 31/12/1999 Other programs (Firefox, Opera, OpenOffice) display this as 1999/12/31 NB: I do not ask how to write unambiguously. (This can be done with <bdo dir=ltr>.) It bothers me that different programs display this file differently.
