When the option 'Store dates in Universal Time' in the General Calendar Options is set, the times are wrong.

It looks like Calendar is still correcting for Time zone/Daylight saving, while the time are already in UTC.

When the option 'Store dates in Universal Time' is not set, the times are correct.

Reproducible: Always

Steps to Reproduce:
1. Set the 'Store dates in Universal Time' option.
2. Create an 'New Event', example 'UTC time check' from 22:00 to 23:00
3. Export that event to a vCalender file

I discovered this when importing iCalendar files. After importing a iCalendar file the times are shown correctly in Calender. But when exporting them to vCalendar, the times are wrong. The iCalendar -> vCalendar is independent of the UT setting. Maybe this is a different bug?

That shows you're using an older copy of Sunbird/Calendar.  Newer copies don't even respect this preference, but instead you get the times with lovely timezone data attached.  The UTC preference was a stop-gap measure when older versions used to only use floating timezones.

This bug is, accordingly, probably invalid.

I'm using the plug-in version 0.2.0.2006011612-cal. 
I noticed that in Sunbird version 0.3a1 the vCalendar export no longer exist. 
Is that option no longer available in Sunbird/Calendar?
From the calendar website <http://www.mozilla.org/projects/calendar/download.html#experimental_stable>:

Stable builds are based on the one-year old code from Sunbird 0.2. This code was well tested and those builds are recommended for those users, that are satisfied with the state of the Calendar extension for Firefox or Thunderbird 1.0. Please be aware that no new features have been developed for these builds and we do not accept bug reports for these builds.

The bugspam monkeys have struck again. They are currently chewing on default assignees for Calendar. Be afraid for your sanity!
