Checked in qtbase 5.15 at ./src/corelib/time/qtimezoneprivate_tz.cpp The systems timezone is detected by $TZ or by reading the target of the sym-link /etc/localtime or by /etc/TZ. None of those is valid in my system, so UTC is selected: According to the handbook I set the timezone in /etc/timezone and sys-libs/timezone-data copies the right file to /etc/timezone. As workaround I used "ln -s /etc/timezone /etc/TZ". Reproducible: Always
I checked that on a Ubuntu system where /etc/timezone is a text file containing "Europe/Amsterdam" (in my case) and where /etc/localtime is the usual symlink. It looks like QTzTimeZonePrivate::systemTimeZoneId only checks for the symbolic link, indeed.

copying the zonefile to /etc/localtime is a good idea, as /usr could be on a separate partition. How about creating the /etc/TZ -> /etc/timezone softlink by default?
So, what can we do here?

Unfortunately that's not the full solution. (The digital clock now doesnt even appear anymore...)

Lars, nvm if I remember incorrectly but please test the linked upstream qtbase MR (patches against qtcore) if you still have a system with separate /usr and/or /etc/{timezone,localtime} as file.

Hi Andreas, sorry for not responding earlier, my day was quite stuffed with online meetings. If you still want to have it tested, I can do so tomorrow...
Wouldn't hurt before we cut a new snapshot, but take your time. It is rather easy by adding qt overlay and building qtcore-5.15.2.9999 instead of latest snapshot in ::gentoo.
