Odd mismatch between timezone handling (monthly view incorrect, edit pane correct for the very same event) #593

Closed user83918491 closed 6 years ago

user83918491 commented 7 years ago

Steps to reproduce

  1. Server timezone: Europe/Berlin 2 . Client/Browser timezone (as recognized by jstz): Europe/Berlin
  2. New Subscription of events with timezone Europe/Copenhagen (e.g. https://tekniskmuseum.dk/events/2017-07-12/?ical=1)
  3. Change to calendar month which has events of step 3. (e.g. July 2017)
  4. Click on one of the events of step 3. such that the right-side detailed edit panel opens (e.g. Parkbanen kører)
  5. Note the difference in shown times in the calendar month view and in the right-side panel for the very same event!

Expected behaviour

Both times, i.e. the one shown on the monthly view and the one in the edit panel, should be equal and correct (e.g. 12:00 in above case).

Actual behaviour

Edit panel shows correct time (e.g. 12:00 in above case) while monthly view shows wrongly shifted event times (e.g. 14:00 in above case).

Server configuration

Operating system: Server: Nextcloud on Raspberry Piv3 Client: Chromium browser on Ubuntu working machine

Server version: (see your admin page) 12.0.2

Calendar version: (see the apps page) 1.5.3.

Did you check this in the js console?

Checked here https://pellepim.bitbucket.io/jstz/

Can you please try executing jstz.determine().name() in the js console of the calendar app, just to be on the safe side? :)

Hello! I see the same behaviour. My time zone is Moscow. In edit mode in nextcloud i specify 14.00, in monthly view i see 13.00. Displacement is 1 hour. If i specify 14.00 in Thunderbird, i will see 13.00 in Thunderbird and in Monthly view of nextcloud.

Please, let me know if i can give you more info. Will glad to do all that is possible.

upd1: time zone Moscow Ubuntu server 16.04 with all freshest updatets Browser: Chrome and firefox

Best regards, Igor

@user83918491 @radioagent Do you use some privacy protecting Chrome plugins?

We've seen similar issues in Tor and Firefox if you modify certain rules in about:config see https://github.com/nextcloud/calendar/issues/711

No, i did not use. Currently i do not see this problem. All works correctly. I use nextcloud 13 , latest version. And latest version of firefox and thunderbird. May be this problem already fixed?

I can't reproduce this bug with the given webcal link. I'm very sure that if this wasn't fixed already in an earlier release, https://github.com/nextcloud/calendar/pull/743 finally fixed it.
