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

Description

[Derek Kaye]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-GB; rv:1.9b5) Gecko/2008041514 Firefox/3.0b5
Build Identifier: Thunderbird: version 2.0.0.14 (20080505); Lightning: 2007120421

For half the year, I use GMT (GMT+0). During summer, myself, and the rest of the country use BST (GMT+1).
If I create an event for, say 10:00 BST during BST and invite attendees, The email and .ics they receive states the time of the meeting is 10:00 GMT - one hour out.
I do not know if this is just a fault with the way my system is set up (The timezone is set as Europe/London) or if it occurs for other time zones.

Reproducible: Always

Steps to Reproduce:
1.Create an event during DST
2.Invite yourself to attend via email
3.Look at the time zone specified in the email
Actual Results:  
Time zone is 1 hour out.

Expected Results:  
Time zone to be local, or the time in GMT (i.e. if the event was scheduled for 10:00 BST, the email would either say

10:00 BST

or

09:00 GMT

What Lightning version do you use? From the build id it looks if you are using an older nightly build. In that case I'd recommend to upgrade to Lightning 0.8 that fixed many timezone related issues.

This may well fix it, I am using 0.7, However, I cannot successfully upgrade. I installed lightning via the Ubuntu apt repositories, and these still have lightning 0.7. On trying to update from within Thunderbird I get a permission denied error. If I run thunderbird as root it appears to install, but the calendar is just a blank white page and is unusable. Been trying for about half an hour now with removing and installing in various combinations with no luck. Guess I'll just have to wait for Ubuntu to fix their repositories.

I cannot confirm that this is fixed - perhaps someone else can?

Install libstdc++5, then it should work. See release notes.

Still no luck I'm afraid :(. I think it might be a 'buntu problem.
