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? --ado
