1390779 - Timezone is not used from /etc/localtime (Debian)

Status: RESOLVED INVALID

(Core :: JavaScript: Internationalization API, defect)

Description

[Georg]

User Agent: Mozilla/5.0 (Windows NT 6.1; rv:50.0) Gecko/20100101 Firefox/50.0
Build ID: 20100101

Steps to reproduce:

I updated to 55.0.1 (64bit) and realised that google appointment invites were off.
Further investigation showed that firefox assumes that I am at UTC time (using https://whatismytimezone.com/ ).
This change is permanent and reproducable 100%

The system is:Linux descere 4.11.0-1-amd64 #1 SMP Debian 4.11.6-1 (2017-06-19) x86_64 GNU/Linux

I reproduced the bug with 56.0b2 (64bit)


Actual results:

Whenever a web page uses the timeone it is off and seems to default to UTC.


Expected results:

https://whatismytimezone.com/ should show my current timezone (Europe/Berlin).
Chromes output is:
The current time is Wed Aug 16 2017 09:56:26 GMT+0200 (CEST)

I gladly provide additional information but I'm not sure what else is useful. Sorry, first bug report!

Is the privacy.resistFingerprinting preference enabled? Because that one changes the default time zone to UTC.

Andre, thank you - even in incognito this seems to have been set.
The text was bold, so I assume I have changed it at some time  - not sure if this was an add-on or myself.

This is clearly a user error not a bug.

Apologies!

No worries! At least this was an easily solvable time zone issue for once. :-)
