Comment 3 for bug 1799339

Please flesh out this SRU test case so that it can be clearly followed by someone unfamiliar with xfce and redshift.

(Likewise, I don't know what to expect on an Ubuntu session wrt timezone adjustment. Given that I have yet to find any option to let me manually configure timezones in recent GNOME, to have the session start to change timezone settings with no way to override through the UI sounds like it would constitute a regression for some users.)
