News are taking their time currently, I am only near my test hardware on weekends. So: yes, timezone configuration works fine, and yes, I should be seing the root password screen but I am not. I just did a test, went back to timezone configuration, and then again forward and directly after the timezone dialog I get to teh root password dialog. All fine second time. But the first walkthrough I really get that welcome screen, and then the error message on top of root password dialog.
