But what if we would like to resist fingerprinting?

Is there some necessary trade-off to get the correct time zone?

This seems like a bug to me.

When resist fingerprinting is enabled then some settings that are exposed to websites are spoofed. In case of the time this means showing the UTC (GMT) time zone. There are more things affected like the user agent that is set to the current ESR release (52.0) on Windows 7 even though I'm on Linux.
