305781 - Time of event is changed for remote calendar user when publishing an event

Status: RESOLVED WORKSFORME

For some of the events I create, when I publish them and a remote user (same
time zone) reloads the remote calendar, the dates are off by a couple of hours.
This doesn't affect all events, just some of them. When I look at the .ics file,
that file appears to be incorrect. This would make it seem like the import of
the remote calendar is not the problem but the export is the problem.

Reproducible: Didn't try

Steps to Reproduce:




I will attach a screen shot of the local calendar and the published .ics file.

Search for 'youth council' in the file. It and the next event (Executive
meeting) are at the same time (as you can see in the screen shot) but in the
.ics file have different DTSTART times.

What version are you using?  (You can get this from Help->About).  If you're not
using a nightly build, could you please try downloading one and testing there?

I am currently using the Thunderbird extention, 2005011112-cal is the version
number. I don't see where I can get any newer version than that. It is the only
one listed in the 1.0/1.0.x/nightly builds column.

That is indeed the latest build of the calendar extension, but Sunbird and
calendar share much of the same code.  Therefore, if you could try and test this
using a nightly sunbird build from here:
http://ftp.mozilla.org/pub/mozilla.org/calendar/sunbird/nightly/latest-trunk/
it would help to determine whether this problem will still be around (and should
be addressed) before/when the next version of calendar comes out.

I just looked in the CalendarDataFile.ics in my Thunderbird profile, and I
noticed something interesting: The Youth Council DTSTART is local time, while
the Council Executive DTSTART has the 'Z' at the end, which I've seen on other
bug reports to indicate time zone info. Not sure why the one has it and not the
other. I think maybe this is occuring when I copy and paste an event (?)

I did another test, and it is the event that I copy and paste that has the wrong
timing (it doesn't have the 'Z'), while all the ones I make from "new event"
have the 'Z'.

I'll try the same with the stand alone Sunbird.

Here is a publish from the Sunbird build. The event on Aug. 27 was "new", and
Aug. 26 was copied and pasted. Notice that both have the 'Z' so I think that
means the bug is fixed in the trunk.

Any word on when a new extension for TB will be available? The new features in
the Sundbird look nice (from the brief look I had). I can't use the unstable
(trunk) version at work.

I'm going to go ahead and mark this as Resolved:WORKSFORME then.  This is done
when the bug appears to have been fixed, but when no specific code changes can
be identified as solving it.  If you find later that this bug has actually not
gone away, you should feel free to re-open it.

It's being worked on.  Soon hopefully :-)  The truly brave tester might try to
build Thunderbird on their own, with the calendar extension enabled, which would
allow for immediate testing.  But building on Windows isn't much fun.
