I wish they'd gone with 2001-02-03T04:05:06 (sub 16 for 24h, obvs) because that at least is in numerical order (and you can use +07 for timezone.) There's surely no date format in existence where month comes first and year comes last -after the time-. Or if they were stuck on 2006, 2006-05-04T03:02:01 but then you get +00 for the timezone which might be weird.
