Calledar meeting request shifts one day

Hi all,

When I create an appointment with outlook 2000 (In caledar options I
switched "Send meeting request using iCalender by default") and I invite
other Attendees, the appointment is not correctly send. In the calendar of
the attendee, the appointment is an all day event on the next day.

The appointment was on 08-12-2004 from 18:30-22:30.
The VCalendar in the mail looks like:
BEGIN:VCALENDAR

But I think the DTSTART value should be: 20041208T183000Z.

Is this a bug in outlook 2000, or do I miss something?

PD

(sorry about my bad english...)
