All day events in a remote calendar (apache 2, webdav; also on icalx.com) are correctly shown in the calendar but the end date in the event list is one day too late.

For local calendars, the event is displayed correctly in the event list, even
after restarting sunbird.

Reproducible: Always

Steps to Reproduce:
1. Create an all-day-event in a remote calendar 
2. Reload the remote calendar



Actual Results:  
After step 1, the event is shown correctly in the calendar AND in the event list.
After step 2, the event is shown correctly in the calendar but with a wrong end date (on day too late) in the event list.


Expected Results:  
Reloading the remote calendar should not change the display.

Joey, 
this is not the same problem as in bug 306157, thus I adviced him to write a new one (to keep one problem per bug). See bug 306157 comment 8 and 9.

Is there a testcase for this?

Attachment: ics-file with an all-day-event

1. Create a remote calendar with the attached file (WebDav, location: file:///C:/.../test.ics). The event is shown correctly on Nov 7 in the calendar but with a wrong end date of Nov 8 in the event list.

2. Create a new all-day-event in this remote calendar. It is shwon correctly in the event list until you reload the remote calendar. After a reload, the same wrong end date as in 1.

3. Import the attached file into a local calendar. This also results in a wrong end date (one day too late) in the event list.

4. Create an all-day-event in a local calendar. It is always correctly shown in the event list.

I can confirm all your steps. Doing this I have noticed the following: 

Open Edit Dialog for any of those all-day events, change nothing and press OK.
--> The all-day event is displayed with correct end date in event list.

Reload remote calendar or restart calendar
--> The all-day event is displayed with wrong end date in event list again.

I tried again with Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.9a1) Gecko/20051209 Mozilla Sunbird/0.3a1+ and found the following:

I created an All Day Event from 20-Dec-2005 to 22-Dec-2005. Then I compared the start and end value displayed in the event list depending on my local timezone:

TZ (as reported in console)        | Start  |  End
-----------------------------------+--------+--------
GMT-1200 (Datumsgrenze Normalzeit) | 20-Dec | 22-Dec
GMT-1100 (Samoa Normalzeit)        | 19-Dec | 22-Dec
GMT-0100 (Azoren Normalzeit)       | 19-Dec | 22-Dec
GMT+0000 (Greenwich Normalzeit)    | 20-Dec | 23-Dec
GMT+0100                           | 20-Dec | 23-Dec
GMT+1200 (Neuseeland Normalzeit)   | 20-Dec | 23-Dec

Seems that this is another issue based on the timezone settings.

Unfortunately, I do not have cycles to work on Calendar stuff these days (just as it's getting to the good part!), so I am a bad owner for these bugs.  To delete the tragically-large chunk of bugspam, search for gregorianabdication.

I talked about this with dmose a few days ago.  It seems to be unifinder only, so it shouldn't block Lightning 0.1.

Just landed some changes today that may or may not help with this.  Be nice to see whether or not the situation is changed.  Can someone please test again with a nightly?
