TimeLine and TimeZone

Is it possible to change the TimeZone used by the TimeLine? You can change the Locale, but it’s not clear to me how that influences the TimeZone. Also, the TimeZone I want to use is not linked to the Locale.

If it’s not possible to change the TimeZone, what TimeZone is used by default by the TimeLine? Is it the TimeZone of the browser?
