OpenSUSE :: Outlook Increments Kontact Invites By One Hour?

Microsoft Outlook increments Kontact invites by one hour. It appears that Kontact and Microsoft Outlook process ical.ics invite times differently. According to an inside source at Microsoft, Outlook is looking for a flag in the ical.ics file that indicates if time is being send in daylight saving time (DST), or standard time. If the DST/ST flag is not present, Outlook assumes the time sent is standard time. Outlook also looks at the time zone. If the time zone indicates DST is active, and the time sent is in standard time, Outlook increments the time by one hour. Kontact does not create a DST/ST flag for the ical.ics files it creates. Thus, all invite times I send to my Outlook clients are off by one hour.I don't know the ical.ics standard.

Is Kontact not implementing an ical.ics standard, or is this DST/ST flag just an internal Microsoft standard? IMHO Microsoft's algorithm for determining DST is inefficient, and not logical. The algorithm relies on the receiver knowing the DST rules of the sender. The logical way is to send time as an offset to universal time. The receiver then adjusts time according to the local DST rules, without having to know about sender DST rules.
