Re: [ISO8601] ISO 8601:2004
- Oh I'm glad of this change. :-) It gets rid of even a YY-MM-DD date
completely, allowing there to be no ambiguity of the date in question.
I always thought the rules for truncation were confusing. The only
reduced precision that I can see as 'ambiguous' is the YYYY-MM one,
because to many people, it's often wrongly used in ranges of numbers
(and years), like 'pp. 356-9' to mean pages 356, 367, 358, and 359; or
'pages 300-80' to mean pages 300 to 380. I often still see year ranges
in essays & the like shown as '1985-90' and '2001-05'. Very ambiguous
to me. I sometimes even see 1998-02 to mean 1998 to 2002 (which has
always been incorrect)!
Out of curiosity, why is the solidus (/) preferred as the date
component separator/demarcator (sp?) instead of just the double hyphen
(--) (which is allowed, but only in situations when the solidus can't
be used), tilde (~), or even endash (–)?
