Re: [dispatch] [Sedate] WG Review: Serialising Extended Data About Times and Events (sedate)

[Francesca Palombini <[e-mail]>]

Hi all,

(CC dispatch for information)

The charter for the Sedate working group has passed the first phase and is now in external review. Additionally, the sedate mailing list has been created. Do go over there and subscribe if you are interested.

Now is the time to let the IESG know of any comment you might have on the charter text.

I am also looking for volunteers to chair the wg. It is ok to volunteer someone you think would be a good fit. I hope that, given the interest in this work, we will not have problems finding chairs, but as a reminder: please do consider volunteering if you support this work, as with no chairs there will be no working group.

Please reply to this thread (dropping the dispatch mailing list), or send an email to the IESG ([e-mail]) or directly to me with any comments on the charter, or volunteering as chair.

Thanks,
Francesca

    RFC3339 defines a format that can reliably express an instant in time, either
    in UTC or in a local time along with the offset against UTC. However,
    datetime data often has additional context, such as the timezone or calendar
    system that was in use when that instant was recorded. Particularly when
    using times for interval, recurrence, or offset calculations, it is necessary
    to know the context in which the timepoint exists.

    It is valuable to have a serialisation format that retains this context and
    can reliably round-trip the additional context to systems that understand it,
    via intermediate systems that only need to know about the instant in time.

    The TC39 working group at ECMA have developed a format that is a good basis
    for this work: draft-ryzokuken-datetime-extended.

    It is anticipated that this document would be a companion to RFC3339 rather
    than a replacement, embedding an unaltered RFC3339 instant along with the
    contextual data.

    It is also within scope for this working group to consider a minor update to
    RFC3339 to allow larger than four-digit signed years, to enable representing
    times further into the past and future.

    It is anticipated that this working group will publish one or two documents
    on the work mentioned above. After that, the working group will close down or
    recharter.

    The working group will coordinate with ECMA International TC39 and ISO TC154.

    Milestones:

      Dec 2021 - Submit extended date and time draft to the IESG for publication
