(Calendar :: E-mail based Scheduling (iTIP/iMIP), defect)

Description

[Anders Larsson]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; sv-SE; rv:1.8.1.11) Gecko/20071127 Firefox/2.0.0.11
Build Identifier: Thunderbird version 2.0.0.9 (20071031) - Ligthning 0.7

When I receive an invitation to an event through mail from a sender with Outlook, I accept the invitation and the event is correctly added to my Lightning Calender with the date and time specified in the invitation. But when I then restart Thunderbird, the event in my Calender has changed to one hour earlier than the invitation and the event earlier said. 

Reproducible: Always

Steps to Reproduce:
1. Accept an event in a invitation from Outlook
2. Check in Lightning that the time is correct as the invitation said
3. Restart Thunderbird

Actual Results:  
The time for the event is now one hour earlier in Lightning

Expected Results:  
The time should be the same as before Thunderbird was restarted.

I'm using Timezone "Europe/Stockholm"...
