Latest OS Update updated on 9th August 2020 at 22:00 US Pacific Time, broke my timezone settings.
When I applied the latest OS Update to my Pinephone, the time displayed changed.
I had automatic timezone detection and location services enabled at the time of updating. The update required a restart, and upon restarting the phone I noticed the correct time in my timezone displayed for a split second, and then it changed. Upon checking the timezone that was detected - it showed Accra, Ghana.
I tried turning off automatic timezone detection and then turning it back on. That did not work. I then tried turning off location detection and turning that back on. It did not work either. I then turned both off and turned them both on - that did not work either.
Workaround: So, I turned them both off, and then restarted the phone. After starting the phone, I then enabled location services, and then enabled automatic timezone detection, and it fixed the time displayed to my timezone.
