International date format
As I understand it, the ISO standard date format is YYYY-MM-DD. link
(I couldn't get anywhere within the ISO web site - it looks like you have to pay for any useful material)
I know Canada adopted this format officially more than 10 years ago, though it doesn't seem to have penetrated much. I use it, as it is unambiguous and mathematically appealing. Raoul and other international readers, what is the de facto standard date format in other countries?
