This is a dupe of bug #1456281 which was fixed on June 22.

So the remaining task is we need to get the version in rc-proposed bumped to a newer version of indicator-datetime

Actually... even though this sure smells like a dupe, now I'm not sure we can mark it as one.

The tz offset fixes in 15.04 landed earlier, and 13.10.0+15.04.20150618-0ubuntu1 is actually the latest build there. <>

Daniel, I'm not able to reproduce this yet. Tested with a fresh flash from ubuntu-touch/rc-proposed/ubuntu, creating both alarms and calendar reminders.

It's an imported calendar from Google, and for example my 16:00 (local time) meeting which just finished is shown for 18:00 later on.

Are there any debug steps I could run through?

Daniel Holbach (dholbach) wrote :

Ahhh. It shows the particular meeting at 18:00 UTC even.

Daniel Holbach (dholbach) wrote :

The timezone of the phone is correctly set to Berlin. date agrees with that as well:

phablet@ubuntu-phablet:~$ date; date -u
Do 9. Jul 16:50:24 CEST 2015
Do 9. Jul 14:50:24 UTC 2015

Daniel mailed me a copy of his calendar and I'm seeing the same behavior.

The interesting issue is that it's not happening for events created in the clock or calendar apps -- just the ones imported from Google calendar.

I suspect it's an issue with how indicator-datetime is handling the timezone strings there. A sample tzid:

I am affected by this bug as well but in my case I not only see the time wrong in the indicator, but also in the Calendar app so I suspect the bug may be in the Calendar app itself.

* I created an event from my Android phone
* I synced Ubuntu Calendar app
* the event is now displayed as starting 2 hours later than it actually is on Ubuntu (I am in UTC+2).

Zubozrout, could you attach the affected ics file or mail it to me at charles.kerr at canonical?

You should find the file somewhere underneath the $HOME/.local/share/evolution/ directory; e.g. $HOME/.local/share/evolution/calendar/system/calendar.ics

Here it is...
Look at this event: Vyzvednout boty na Krakovské
In calendar and indicator I see the event starts at 11:30 although it should start at 9:30 as it is in the file.

It must be that timezone is somehow not understood by calendar app.

Isn't the indicator level fix sufficient?

The qtorganizer will have the same TZ problem. It will need a similar fix.

Same bug with new OTA 6 (mako).

To reproduce:
Create an event in the calendar app for, says, tomorrow at 3PM.

The event is shown at 1PM in indicator-datetime


@nicolas which tz are using in the phone?

Sorry, I forgot to mention. My timezone is Europe/Paris (ie. GMT+2)
