378855 - One hour offset when clicking on day view to open event (TZ is Asia/Jerusalem)

Status: RESOLVED DUPLICATE of bug 367378

(Calendar :: Lightning Only, defect)

Description

[Barak Ori]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.11) Gecko/20070312 Firefox/1.5.0.11
Build Identifier: Thunderbird 1.5.0.10 (20070221) with Lightning 0.4a1

I'm sure this has relations to multiple bugs I saw while searching, including (especially) bug 367378 but what I see is different: When I see the single day view and double click at 9:00 AM, the "New Event" dialog shows From=10:00 AM and To=11:00 AM. If I actually save the event, it shows up in the day view at 9:00 AM.

I don't know if that's related, but to see what time the event is actually at, I opened two events one at 10:45 AM and another at 11:45 AM (times as shown in the day view). It was 10:37 AM at the time. None of the events popped up in the next few minutes.

Notes:
1. I assume this anomaly only happens during DST. Also, I'm aware of the difficulties of the Asia/Jerusalem timezone, but this looks like the two components take their TZ definitions from different places, since I'm opening an event for today (while DST is observed).

2. I chose component "Lightning Only", but that might not be true. I only use Lightning.

3. Probably related - when I'm receiving an invitation from OutLook 2003 (SP2) it shows up one hour too early on my calendar (the invitation was for 4 PM, and after adding it to the calendar, I see it at 3 PM).

Reproducible: Always

Steps to Reproduce:
1. View the today in Lightning.
2. Double click anywhere to add an event based on the time you clicked on. Let's assume you click on 9:00 AM.

Actual Results:  
The "New Event" dialog shows the From time as 10:00 AM

Expected Results:  
The "New Event" dialog should show the From time as 9:00 AM

I've added a short video screen capture showing this bug. The file is 761KB, so I can't attached. I put it at http://xmixdrix.com/tools/lightning-bug.avi.

Barak, can you export your events to ics-file and attach this here, please.
What timezone is set in Lightning (probably Asia/Jerusalem, as I read it) and what timezone is set in Windows. And can you please try with a recent nightly build.
Thanks, Sebo

Attachment: Calendar exported as ics

Note: I assume the calendar has some Hebrew characters, encoded in iso-8859-8 (These are probably meetings I got from OutLook), still, enough events have ascii only names.

My Timezone is set to /mozilla.org/20050126_1/Asia/Jerusalem, and in Windows it's (GMT+2) Jerusalem with automatic DST adjustments. I can try the nightly build, but probably not today. Also, could it be working correctly in the 0.3 version?

No, I think your issue has been fixed with version 0.3.1 Please try that or a recent nightly. Thanks.

bug 367378 is the one I was thinking of.

But I'm actually using version 0.4a1. I was asking if there's a chance this was introduced in 0.4.x and I should revert to 0.3.1 (I said 0.3 meaning 0.3.x - the latest stable). I only tried 0.4.x since I was hoping to get FreeBusy integration with our OutLook users, but it's not there yet, so if this was introduced in 0.4.x, I'll revert to 0.3.1.

Comment 8

[Sebastian Schwieger]

The question is: what date is the nightly 0.4a1 from. This can be seen in the Add-On Manager. There have been 0.4a1 builds before 0.3.1 has been released. Your timezone definition (/mozilla.org/20050126_1) says that this is a pre-0.3.1 version. So, probably the best for you is to use a recent nightly, because "going back" to 0.3.1 will likely cause database version conflicts.

I installed 0.5pre (nightly build as of 2007-04-29 10:24 Israel DST) don't know how to obtain the exact version. The option dialog has changed and now doesn't show the actual timezone definition, but it's probably newer.

I can confirm that double-clicking at a certain time opens the "New Event" dialog with the right time filled in. In addition, all my tasks are now shown "an hour later". Meaning - in the past, when I tried to open a task at 1:00 PM, in the dialog it showed as 2:00 PM, and when saving it was showing at 1:00 PM. Now, after upgrading, the task shows at 2:00 PM.

It looks like this will also solve the OutLook 2003 integration. Also, the day/week/month view look much nicer now ;-) Thanks.

Nah, the OutLook thing isn't solved. I asked someone using OutLook 2003 to invite me for something today at 4:30 PM, and it's now listed at 5:30 PM in my calendar. But adding an event works fine :-)

Comment 11

[Barak Ori]

Wait - it works! (Sorry for flooding this bug). I checked the invitation I got from OutLook, and it was sent as GMT+2, while in the summer Asia/Jerusalem is GMT+3. I confirmed the clock on that person's machine wasn't setup correctly. I asked another person to send an invitation through OutLook 2003, and it worked fine. So as I see it now, everything works fine now. How can I help with getting FreeBusy to work?

To clearly identify a nightly build you need the version number and the build ID as shown in the Extension Manager (Add-ons Manager in Thunderbird 2), e.g. "Lightning 0.5pre (2007042804)".
