Currently brave browser haven't an option to set custom time zone. So it seriously destruct anonymous status. Because when I connect to some VPN I want to set time zone of server location to prevent leak. Some shit is exist in Linken Sphere Browser.

I'm running Brave in a Fedora 30 singularity instance on a Centos 7 host [1]

However, this detects my timezone incorrectly as UTC, causing problems with some sites (remember the milk in particular).

It is not really clear to me how Brave determines the timezone. Just doing 'date' in a container instance shows the correct timezone. So I guess is that Brave uses some other method that fails and therefore defaults to UTC.

Being able to specify the timezone would solve this problem.

For those interested in lying about their timezones, use TZ=Etc/UTC brave when launching. Brave respects the TZ environment variable on relevant platforms.
