Outlook not correctly importing .vcs file

[tpro]

Outlook's support of "floating time" format in vcalendar files (.vcs) is not
working.

Outlook always interprets the DTSTART and DTEND fields of the .vcs as UTC,
whether or not the DATE-TIME string is terminated with the "Z".

According to RCF 2445, the "Z" indicates UTC, and the absence of the "Z"
indicates local ("floating") time.

Example:
DTSTART:20090822T080000
should be imported as "8:00 am" local; instead, it's being imported as 01:00
am local (PDT) time.
Compare to
DTSTART:20090822T080000Z (this is 01:00 am PDT)
and
DTSTART:20090822T150000Z (this is equivalent to 08:00 am PDT)

Outlook has never supported 'floating' appointments - they are always pinned
to a specific UTC time and if you change the time zone, the appointment time
changes. Even all day appointments change to 24 hrs over 2 days (ie, 11 pm -
11 pm or 1 am - 1 am) when the time zone is changed.

Outlook 2010 now supports all day even that stick to the date but timed
appointments will move with the time zone changes (you can select a time
zone for appointments so you don't have to think about the correct time in
that zone while in a different zone)

When its first opened, it will be on 9 -11, but when you change the
computer's time zone, it will stay on 9-11 in the time zone you used when
you added it to the calendar. It will not float to 9 -11 in every time
zone - but it will be added to 9 -11 if you reopen it from the hard drive.
(http://slipstick.me/jing/time.png) That is not how Outlook works. It
works as expected in Outlook 2010 and 2003 - those are the only 2 versions I
have accessible at the moment. You said it works like this in 2000 also but
not 2002?

;140230']Outlook has never supported 'floating' appointments - they are
always pinned
to a specific UTC time

Many Thanks for your reply. Unfortunately it is not correct.

I run outlook 2002. The VCS file below works as a floating time, as
their is no "Z" after the DSTART & DEND fields. This appt comes up on my
computer as 9am to 11am, no mater what timezone I set OUTLOOK to.

Code:
--------------------
BEGIN: VCALENDAR
PRODID:-//Microsoft Corporation//Outlook 9.0 MIMEDIR//EN
VERSION:1.0
BEGIN:VEVENT
DTSTART:20100504T090000
DTEND:20100504T11000
UID: Cars.PoolBooking.
SUMMARY;ENCODING=QUOTED-PRINTABLE:Meeting
PRIORITY:3
END:VEVENT
END:VCALENDAR:

--------------------



This Appointment is linked to UTC as there is a "Z" after the DSTART &
DEND fields.

Code:
--------------------
BEGIN: VCALENDAR
PRODID:-//Microsoft Corporation//Outlook 9.0 MIMEDIR//EN
VERSION:1.0
BEGIN:VEVENT
DTSTART:20100504T090000Z
DTEND:20100504T11000Z
UID: Cars.PoolBooking.
SUMMARY;ENCODING=QUOTED-PRINTABLE:meeting
PRIORITY:3
END:VEVENT
END:VCALENDAR:

--------------------


So I think my office party theory stills stands, but I am very happy
to be corrected.

As expected means that opening the vcs from my hard drive opens it with the
time of 9 -11. When I save it to the calendar and change the time zone to
PT, the 9 -11 appointment moves to 6 -8. This is all expected.
http://slipstick.me/jing/tz.png - this is Outlook 2003. I pasted the vcs
code into notepad and saved, then opened it. Changed the time zone, reopened
the vcs. It's 9 am in the current time zone.

This worked in both Outlook 2003 and 2010 the other day.

However, today its acting weird in outlook 2010/Win 7. When I change the
time zone and reopen the vcs, the time adjusts - based on the differential
between the old time zone and the new one. It is not opening based on the
UTC - I'm in ET (-4 right now) and the first appointment is for 9 am.
Saving it and changing the time zone then reopening the vcs from my hard
drive - and the vcs has adjusted so its still on 9 AM ET.

Because of this weirdness, I decided to bring up Outlook 2007. It uses UTC
time - the appointment is 5am. This is what you see in 2000 and 2002,
correct?
