Hi,

when defining an alarm trigger through the dialog box, we have the possibility to define the trigger by reference to the "end" of the event and not its beginning, but these alarms never raise !

More the less, when using ics file calendar, the VALARM component doesn't inform that it has been defined upon the end of the event, and not its beginning.

Reproducible: Always

Steps to Reproduce:
1. Create an event
2. Open the reminder custom dialog box
3. Set up a trigger to some time before or after the event "ends"
4. Close the dialog box, and wait
Actual Results:  
No alarm triggering

Works fine for me using Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.18pre) Gecko/20080917 Sunbird/0.9 and local storage calendar. The alarm dialog was shown at the correct time. I exported the event to the iCalendar format and it clearly shows that the alarm is related to the end date:

ok, this is my fault, it works fine in 0.9. I took 2 brand new calendars (one local, one in ics file), and both alarms raised and were present in ics file (after export for the local calendar).

But, in 1.0pre, I did the same (2 brand new calendars, one local and one in ics file), and the problem occured with both. The alarms haven't raised, and VALARM component is absent of both ics file (after export for the local calendar).

Here is the resulted ics (similar in both cases):

    BEGIN:VEVENT
