Precedence: list

I sent this from naruse@airemix.jp but it seems not accepted,
so I post this again.

Anyway,
draft-ietf-httpstate-cookie-02 says in 4.1.1. Syntax,

   cookie-date       = <rfc1123-date, as defined in RFC 2616>

But you know, cookie-date is not rfc1123-date.
It's a original exotic date format.

   rfc1123-date = <Wdy, DD Mon YYYY HH:MM:SS GMT>
   rfc850-date  = <Weekday, DD-Mon-YYYY HH:MM:SS GMT>
   asctime-date = <Wdy, Month dd HH:MM:SS YYYY>
   cookie-date  = <Wdy, DD-Mon-YYYY HH:MM:SS GMT> ; not RFC 2822

Current description causes misunderstanding.

= 5.1.1.  Dates

Why it needs such a complex definition?
Its demerit is clear in ticket #7.

It seems to intend to change cookie-date from current exotic format
to exact rfc-1123-date or something in future, but why?

Recently, many specs are using ISO 8601 Date and Time format (or other
related specs).
So formats they really needed are only exotic and ISO 8601.
Current algorithm make things too complex but still can't express timezone.
So I object this.

If make cookie-date exotic or RFC 3339 (ISO 8601 related RFC),
the syntax would be following:

  cookie-date      = rfc3339-datetime / obs-cookie-date
  rfc3339-datetime = <date-time, as defined in RFC 3339>
                   ; YYYY-MM-DDTHH:MM:SSZ
                   ; YYYY-MM-DDTHH:MM:SS+09:00
  obs-cookie-date  = <Wdy, DD-Mon-YYYY HH:MM:SS GMT> ; not RFC 2822
