Ah, the power of the obsessive mind. I'm impressed. I can see that RDF is definitely going to rule the world! I am very disappointed in weatherunderground tho. Everybody within 2 kms of here knows Roberts Creek! :-) > -----Original Message----- > From: public-rdf-dawg-request@w3.org > [mailto:public-rdf-dawg-request@w3.org]On Behalf Of Dan Connolly > Sent: Wednesday, April 07, 2004 8:30 PM > To: Howard Katz > Cc: RDF Data Access Working Group > Subject: RE: agenda: 8 Apr RDF Data Access WG teleconference (fun with > people, places, and timezones) > > > > On Wed, 2004-04-07 at 16:39, Howard Katz wrote: > > To double-check: We've just gone to Daylight Savings Time, so > that's 8:30 am > > on the West Coast, 11:30 am in Boston? > > I don't trust myself to do this sort of calculation, and it's hardly > fair for me to do it for one WG member without doing it for everybody. > So let's get the machine to do it, shall we? > > I trust myself to find the name of a nearby city or airport from contact > information WG members gave in their introductions.

So yes, that's 8:30 am on the West Coast. (details on how all the above magic happens are in the makefile: http://www.w3.org/2001/sw/DataAccess/Makefile ) I think there's a use case or two in there: I'd sure rather use RDF data access technology than regexp-scraping out of HTML for the weatherunderground mapping from placenames to lat/long and timezone and for the timeanddate.com mapping from UTC time to time in various cities around the world. > > Thursday 15:30-17:00 UTC 8 Apr 2004 for 60 to 90 minutes > > Zakim Bridge +1.617.761.6200, conference 7333 ("RDFD")> -- Dan Connolly, W3C http://www.w3.org/People/Connolly/ see you at the WWW2004 in NY 17-22 May?
