           Summary: KOrganizer does not properly display appointments that
                    reference time zone data stored in ICS files, for
                    importing old calendars, accepting sinlge appointments
                    from Kmail or importing single events.
           Product: Akonadi
           Version: 4.7
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: ICal file resource
        AssignedTo: kdepim-bugs at kde.org

Broken ICS that triggers the bug.

Version:           4.7 (using KDE 4.7.0) 
OS:                Linux

It seems that with the recent switch to Akonadi-backed iCal resources,
KOrganizer has lost the ability to put appointments to the proper local time.
This is a regression from KDE 4.6.3 to 4.7.0.

I have attached a small ICS to showcase this.

Reproducible: Always

Steps to Reproduce:
Import the attached ICS file into KOrganizer using Akonadi for ICS resources as
a new calendar. On a system that does not provide the referenced "Eastern ..."
time zone from the file, but should rely on the provided time zone information
from the ICS.

Actual Results:  
The event is added at the exact time referenced in the ICS, without honouring
the time zones. It ends up at 7:30 in my calendar, which is the raw time in the
ICS. I am locally at Europe/Berlin, and the event is at "Eastern Standard".

Expected Results:  
The event should be at 13:30, taking into account the time zone differences
between local time zone and that in the ICS file.

KMail displays the proper time in the invitation, which is confusing. This *has
worked* with KOrganizer from KDE 4.6.3, *not* using the Akonai-iCal resource,
hence this is likely a bug in there.
