I think this has long been needed.  One thought re: scaling - could the
existing NTP/SNTP hierarchy be used to also hold and distribute the timezone
data? That way the time servers also could be the timezone servers;  the
data changes fairly infrequently but when it does it is with short notice,
it would be nice to have it spread out through a tree structure fairly
quickly.  I don't think the update would cause significant load to the
servers, and the hierarchical nature of NTP/SNTP would, it seems to me, make
sure queries are handled as locally as possible.

This is likely of interest to all iCalendar/CalDAV etc folks. Discussion of
the proposed working group charter should initially take place on the
apps-discuss list.

Cyrus Daboo has proposed a new working group in the Applications Area, and
I'm initiating charter discussion on it:

We'll have the charter discussion here on apps-discuss.  Assuming a working
group comes out of this, we'll create a new mailing list for the actual
work, once the charter is done.

Comments on this charter are welcome.  I expect to put it on the 10 July
IESG telechat for initial approval, after which it will go out for IETF and
external review.  So, comments here by 4 July, please.

Barry, Applications AD
