It is not a camera or card issue (tried with another one). Under windows a new created photo shows correct date. There is write access to the card in Linux. I can see that unmount is sometimes delayed if using cards that are full of pictures. Also I get a shift each time I add a new picture and unplug/plug the sd-card. That shift doesn't seem to happen if a) no new picture is added, b) the process of whatever it doesn is completed last time.
I did remember I once changed "timedatectl" to get it compatible to Windows. Otherwise the time has to be adjusted after each change of boot. To make clear that this is not the issue I set it back (see below). But even after that, and even after reboot - the issue keeps same. A new created picture is shifted to January 2021 and the other pictures are inbetween moved to May 2021 - crazy shit. Who is writing to my SD-Card and why? My suspect is a picture programm, but how to find that? Mate is setup to do no action when mounted (so not open shotwell or caja). ~$ timedatectl Local time: Sa 2020-12-12 18:55:33 CET Universal time: Sa 2020-12-12 17:55:33 UTC RTC time: Sa 2020-12-12 17:54:39 Time zone: Europe/Berlin (CET, +0100) System clock synchronized: yes NTP service: active RTC in local TZ: yes Warning: The system is configured to read the RTC time in the local time zone.
