> NOTE: ISO 8601 defines date and time separated by "T". Applications using this syntax may choose, for the sake of readability, to specify a full-date and full-time separated by (say) a space character.
Sure it does. It's the shortest way to specify a date within a period of a year surrounding the current day... Which means it's a date format that should only ever be spoken, not committed to written record.
And if you are using something else, especially if it’s something like XX-XX-XX, specify what you mean by that!
