guix browsers timezones are set to GMT

guix browsers timezones are set to GMT

[divan]

Hi Guix

I see timezones in browsers on my guix system are set to GMT.

An example would be qutebrowser and guessing ungoogled-chromium which
use qtwebengine.

Example website is browsing to
https://play.grafana.org/d/000000012/grafana-play-home?orgId=1

in qutebrowser one can run ":jseval alert(new Date().toString())" From
https://play.grafana.org/ and it reports GMT+0000 .

Browsing to the above with epiphany results in the correct local
timezone being set.

I understand for fingerprinting and privacy it's nice to have a
website not detect your correct timezone, though I'd prefer to have my
timezone detected correctly in these browsers.

Does guix do something special in the packaging of
qutebrowser/ungoogled-chromium/qtwebengine that causes this?

It seems to not occur on my colleagues systems with the same browsers.

I see my timezone on my system like so:

(operating-system
 (host-name "example")
 (timezone "Africa/Johannesburg")
 (locale "en_US.utf8")

For what it's worth, there's a bug report here matching the issue you
describe. The issue appears to affect quite a number of programs.

Hmm, I thought we had fixed that particular bug with commit
2a80d9e55299214a3f0b4f585767b4c81c9d5c7d.

Are you still experiencing this problem with the Evolution calendar?

Had a look at that thanks.

Seems icecat works, when the privacy feature (ResistFingerprinting) is
disabled in about:config .

chrome and qutebrowser however do not report the correct time for me.

str1ngs in irc mentioned:

<str1ngs> divansantana and QDateTime works as well
<str1ngs> it's something qtwebenine or javascript related

Hi!

IceCat has a privacy feature turned on by default that, among other
things, has it not announce its timezone.

You can turn that option off by going to “about:config” in IceCat and
then turn off “privacy.trackingprotection.enabled”, IIRC.

However, that’s coarse-grain.  I’d love to have the option to just turn
off timezone concealing; anyone knows how to do it?

Thanks,
Ludo’.
