The time zone doesn't change automatically. I'm pretty sure we have some bugs in regards to this that geolocation doesn't change the timezone. You would have to adjust the timezone manually. If you are connected via wifi or SIM, then it should adjust to make sure you have the correct time on the timezone that's selected.

I had a SIM and data connection, that is why I expected the time change.
