Use ISO standard date format for %x; this is more appropriate than the American date format, which confuses non-Americans. Especially for dates like 01/02/03; the ISO date 2003-01-02 is much clearer for everybody, and it sorts correctly too.
Does "ISO standard date format" hear mean that YYYY-MM-DD is what the ISO version of the C language standard requires, or does it mean something else? Sorry, I should have been more specific. YYYY-MM-DD is from an ISO standard specifically for date formats. I've been told it's ISO 2014, and that it's about 20 years old -- I don't have a copy of the standard myself, though. The C Standard itself, of course, doesn't require any particular format here, but I think the ISO format is a good choice.
