Saved Alarms and Timers Disappearing After Reboot

I found this thread since for the first time (ever) I have this same issue: all timers and alarms are cleared at each reboot on my Xperia 10III 4.5.0.24. What did I change since last time I actually used alarms or timers? I installed the alternative fonts following these instructions elsewhere in the forum: Change Default Font - #2 by nephros . I also installed LXC Containers application from Chum and has rebooted after that a few times without looking at the alarms. To be studied.
2024-01-13 how I fixed my particular problem by resyncing user’s timed-qt5.service:

Summary
  • If after the restart of the phone, before you launch the jolla-clock application you get an empty list from the command timedclient-qt5 -L (if not available in /usr/bin, install it with devel-su pkcon install timed-qt5-tools) ;

  • If there is a file ~/.timed/events.data which contains the timer and alarm settings from the jolla-clock application ;

Then you are in the same same situation I was, and you can attempt the below procedure to recover :

  1. Check the file, generated from jolla-clock application settings in ~/.timed/events.data ;

  2. If it contains your previous settings or you are otherwise satisfied with it, skip the next step ;

  3. Otherwise, use the jolla-clock application and set the alarms and timers as you want, and quit the application and go to point 1 ;

  4. Give command systemctl --user restart timed-qt5.service ;

  5. Give command systemctl --user status timed-qt5.service and verify that the service is running ;

  6. Verify that a similar list (but in different format) than in ~/.timed/events.data file is given out by the command timedclient-qt5 -L ;

  7. Open the jolla-clock application and verify that all alarms that you want to be enabled are enabled ;

  8. Quit the jolla-clock application ;

  9. Restart the phone ;

  10. Open the jolla-clock application and verify that all alarms and timers and their settings are persistent - that they have survived the restart.
