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

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 (iesg at ietf.org), or directly to me with any comments
on the charter, or volunteering as chair.
Thanks,
Francesca

Charter: https://datatracker.ietf.org/doc/charter-ietf-sedate/
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
