Component: Add-Ons: General → Lightning Only
OS: Unspecified → Windows 10
Product: Thunderbird → Calendar
Hardware: Unspecified → x86
Version: 60 → Lightning 6.2.3.1
Lightning version 6.2.4 (this option is no available)
Version: Lightning 6.2.3.1 → Lightning 6.3
I cannot reproduce this here. What is your OS timezone and which zone is configured in TB Options > Calendar > General? Can you reproduce the issue, if you disable all addons but Lightning and restart TB?
Flags: needinfo?(dbastreghi)
Windows timezone: UTC -03:00 (Brasília/Brazil) TB timezone: América/São Paulo. Yes, the issue still happen if I disable all addons.

Hi. I have made some tests. When an event is created in a local calendar, it works fine. The problem just happen when an event is created on a CalDav calendar. The Horde/PHP timezones on server are right (America/Sao_Paulo). On my cellphone Android, I use DavDroid app. It's works perfectly. The events created on my cellphone appear with right date and time on server and on TB. The events created on Horde webmail appears with right date and time on my cellphone and on TB. The issue happens just when I create a event on TB. It seems like if it is sending the wrong timezone to server. Checking the console, the information sent by TB to server is... - - - - CalDAV: send: BEGIN:VCALENDAR PRODID:-//Mozilla.org/NONSGML Mozilla Calendar V1.1//EN VERSION:2.0 BEGIN:VTIMEZONE TZID:America/Sao_Paulo BEGIN:DAYLIGHT TZOFFSETFROM:-0300 TZOFFSETTO:-0200 TZNAME:-02 DTSTART:19701101T000000 RRULE:FREQ=YEARLY;BYDAY=1SU;BYMONTH=11 END:DAYLIGHT BEGIN:STANDARD TZOFFSETFROM:-0300 TZOFFSETTO:-0300 <---- MAYBE HERE IS THE PROBLEM????

Severity: normal → critical
Indeeed, the coincidence of TZOFFSETFROM:-0300 and TZOFFSETTO:-0300 in Sao Paulo standard time is looking odd since Sao Paulo has also DST. We have that definition in our zones.json [1] and it's there that way since we intoroduced zones.json. I assume this now becomes obvious along with the changes to datetime formatting, but the culprit is the wrong definition. In zones.json there are other zones with the same pattern (no offset transition, but DST present), too, e.g. [2]. This is probably an issue in update-zones.py (or a lack of checking what's carried forward) - Geoff, can you take a look at it, plesase?

I think the problem's actually in the tool update-zones.py calls, and affects all Brazil zones with DST. I'll need to take a closer look tomorrow.
Severity: critical → normal
Flags: needinfo?(geoff)

Let's confirm the problem is the faulty zone information. Here's a copy of Lightning 6.2.4 with the zones fixed. You should be able to install it over the top of the existing one. You'll have to remove it at some point or automatic updates of Lightning will stop happening.

Great!!! It worked.

Okay, well that's a start. I opened a bug about it in the upstream tool, but I'm not hopeful of a quick fix. In the meantime I guess we just fix the zones file by hand and try not to break it? What do you think, MMD?

Summary: Lightning is saving events with wrong hour in 2019 → Error in definition of Brazil time zones with DST

Can you please reference the upstream bug here? I don't see a related message on the tz mailing list [1]. Is the report about the definition itself? If it is, I'm wondering why this hasn't been detected before - either for Lightning or any other consumer of the olson database, since we use and obtain the current definition for quite some time now.

We can edit zones.json maually to fix the issue, but if so, we should probably fix bug 1502832 to update to the latest definition before and make the update script to issue a warning about the need for postprocessing until upstream fixed the issue.

It's not the database's fault (AFAICT) but the tool we use to change it to ical format. I'm not really happy using it as it's a revival of a fork of something else, but it's the best we've got.

Here's the issue I should've linked before: https://github.com/benfortuna/tzurl/issues/34

Comment on attachment 9038156 [details] [diff] [review] 1515937-brazil-1.diff Thanks, the fix itself is an appropriate bandaid until it is fixed upstream, but I would appreaciate if we can do an update to the latest tz version (bug 1502832) before applying (and uplifting) it to reduce the risk of another regression. Also, can you add a note that gets displayed when running the update script to remind the updating person to re-apply the fix? r+ with that added and the tz definition updated.

Can you please crosscheck the tz update - something is fishy, Asia/Tokyo got removed the tzname.

I noticed that and didn't check it. :-/
