           Summary: different timezones in one ical file are not recognised
           Product: korganizer
           Version: unspecified
          Platform: SuSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: korganizer-devel kde org
        ReportedBy: bart geesink org


Version:            (using KDE KDE 3.5.7)
Installed from:    SuSE RPMs
OS:                Linux

I tried to import a google ical calender file into Korganizer and I noticed that it fails to display the times correctly. The ical file itself has two timezones: The one where I used to live (GMT +1) and the one I am living now (GMT+7). The second one is not displayed correctly, but is 6 hours off. When I import the same ical file in Mozilla Sunbird it does display correctly. I guess korganizer does not know how to handle two timezones in a ical file. I looked inside the ical file and I see these two entries at the top:

 X-WR-TIMEZONE:Asia/Phnom_Penh
BEGIN:VTIMEZONE
TZID:Europe/Amsterdam
X-LIC-LOCATION:Europe/Amsterdam
BEGIN:DAYLIGHT
TZOFFSETFROM:+0100
TZOFFSETTO:+0200
TZNAME:CEST
DTSTART:19700329T020000
RRULE:FREQ=YEARLY;BYMONTH=3;BYDAY=-1SU
END:DAYLIGHT
BEGIN:STANDARD
TZOFFSETFROM:+0200
TZOFFSETTO:+0100
TZNAME:CET
DTSTART:19701025T030000
RRULE:FREQ=YEARLY;BYMONTH=10;BYDAY=-1SU
END:STANDARD
END:VTIMEZONE
BEGIN:VTIMEZONE
TZID:Asia/Phnom_Penh
X-LIC-LOCATION:Asia/Phnom_Penh
BEGIN:STANDARD
TZOFFSETFROM:+0700
TZOFFSETTO:+0700
TZNAME:ICT
DTSTART:19700101T000000
END:STANDARD
END:VTIMEZONE

Then this entry is displayed correctly (and is created by Korganizer). My timezone is set to Asia/Phnom_Penh, meaning that this entry is displayed at 19.00 + 7 hours = 0200

This one is not (created by google calender). It will be displayed 7 hours too late, meaning it does not recognize that it is planned in my own timezone.
