Except that that's not true. yyyy-mm-dd is the thing that will sort ok.

I suspect that a significant percentage of people who are used to middle  
endian will use it even in the 1996-09-02 version.

As long as none of these is here to get offended, I'll say that this  
proves that the combination of stupid formats with stupid people is  
harmful.

Also, I'll suggest that 01Jan02 *will* be gotten wrong by some people. Use  
4 digit years, Lars.

(Oh, one minor point. 4 digit years actually buy a lot more than 8000  
years iff there are delimiters around the number. Both 123456-12-31 and  
31Dec123456 are perfectly parsable, should you ever need them, and also  
very obvious extensions.)
