ICalendar - Mozilla - Outlook compatibility

Hi.

    An application I'm developing writes ICalendars for repeating=20
events. It would be desirable (almost necessary) that those ICalendars=20
could be imported in Outlook 2002 and Mozilla Calendar. Outlook 2002=20
supports the property VTIMEZONE -with some restrictions- but Mozilla=20
ignores it and interprets DTSTART (and DTEND) as local time. Specifying=20
DTSTART (and DTEND) in UTC time format makes Mozilla at least to=20
calculate the correct local time, but without considering time zone=20
shifts (from DST to Standard Time or vice versa).

    So it is impossible to have an ICalendar with a repeating event with=20
dates on both sides of a time zone shift correctly imported in Mozilla=20
Calendar but I would like that, at least, offset to UTC was considered=20
but specifying also the VTIMEZONE property to let ICalendar be correctly=20
imported in Outlook.

Is this possible?

Please, excuse me for my poor English.
