Wrong time for events from Outlook CALDav plugin

[drschwabe]

Is anyone else using Cozy in combination with Outlook ? (via https://github.com/aluxnimm/outlookcaldavsynchronizer)

We are getting incorrect times. For example, you create an event in Outlook and when the event is synced to the server the time is off by 6 hours. Even though in Outlook, even after closing the program and loading it back up (syncing to the server again), the time appears correct.

Possibly has something to do with sync, in the sync logs this error is shown:

Deprecation warning: moment().zone is deprecated, use moment().utcOffset instead. https://github.com/moment/moment/issues/1779

Syncing from iPhone works fine - only seeing the odd timing with events from Outlook.

Hi @drschwabe, thanks for experimenting with outlook and reporting your bug.

This sounds like a timezone bug, could you tell us 1 - the timezone your computer running outlook is in. 2 - the timezone your cozy server is configured in (visible through the settings page of your cozy home)

Also, just to be sure, are you running outlookcaldavsynchronizer > 0.99.3 ? It appears there was some TZ issues in older versions.

[drschwabe]

1. The computer running Outlook, is on (UTC-07:00) Mountain Time (US & Canada)
2. Timezone in Cozy is America/Edmonton

Using the latest release of outlookcaldavsynchronizer 1.2.2

Thanks.

Thanks for the details, we will take a look at this when we have some time.

I cross posted the issue to the Outlook CalDav plugin repo. Between all of us maybe we can solve the problem:

Hi,

I updated the issue mentioned above: https://github.com/aluxnimm/outlookcaldavsynchronizer/issues/66#issuecomment-233198276 :blush:

I think I have the same issue, but with Evolution, the standard email and calendar application for GNOME desktop. New appointments change by 7 hours on save -- which matches the time zone difference between me (Pacific Daylight Time, in the US) and the cozycloud.cc servers (which are in France, I assume).

I originally reported my problem to the Evolution developers. When I shared some debugging output, they said that the error seems to be happening on the calendar server.

The conversion of the TZID is all fine, but the server also changed the times, from 12:00 to 05:00 for the DTSTART and similarly from 13:00 to 06:00 for the DTEND.

See the GNOME Bugzilla thread for some more debugging information.

This bug is due to the fact Cozy doesn't work well with timezones. It is an issue independent of the client used.

[Dinduks]

This bug was apparently fixed in https://github.com/aluxnimm/outlookcaldavsynchronizer/issues/66#issuecomment-243001972.

Could you please update us regarding the fix in Cozy?

Thanks!

If they changed the timezone to be in the "standard" list (like Europe/Paris) it will work as-is. If it still requires VTIMEZONE support, I am afraid you will have to wait a bit longer that we develop it (which is somewhere on the roadmap).
