http://bugzilla.novell.com/show_bug.cgi?id=494960 Summary: Kontact calendar does not implement daylightc flag from rfc2445 spec for ical.ics file. Classification: openSUSE Product: openSUSE 11.1 Version: Final Platform: 32bit OS/Version: openSUSE 11.1 Status: NEW Severity: Normal Priority: P5 - None Component: KDE4 Applications AssignedTo: kde-maintainers@suse.de ReportedBy: parthenolide@gmail.com QAContact: qa@suse.de Found By: --- User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.8) Gecko/2009032600 SUSE/3.0.8-1.1.1 Firefox/3.0.8 When Kontact sends an ical.ics invite file it does not include the flag "daylightc", or "standardc" as specified in the rfc2445 specification. Microsoft Outlook expect invites to contain either the "standardc" flag, or the "daylightc" flag. Since Kontact invites do not include this flag, Microsoft defaults to interpreting time sent as standard time. If the local invite time is daylight saving time, Microsoft Outlook increments the invite by one hour. Reproducible: Always Steps to Reproduce: 1. 2. 3. The rfc2445 specification is about 10 years old. Apparently, Microsoft updated Outlook with the last Daylight Saving Time changes, and changed the algorithm used to determine daylight and standard time. The old algorithm is actually more efficient than the new. The most efficient algorithm is to determine invite time as a function of time sent and UTC offset, and then adjust this time to local daylight/standard time rules. The invite receiver doesn't really need to know the sender's time zone and daylight/standard time rules. However, the standard requires that this information be sent. And, apparently Microsoft is using the daylightc/standardc flag as its algorithm for adjusting time. The severity of this bug for most users is "normal". However, I am lucky to live in the Pacific Time Zone and can work around this problem by setting my clock to America/Phoenix. America/Phoenix is year round Mountain Standard Time.
