   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.
