Hi,
There was an issue with time introduced when working on NTP precision around version 1.33. I believe it was solved in the 1.37 release for QuadCore.
Your backup does not include the settings of the QuadCore, so I can't see what you have for NTP server IP. It should be displayed in white in the UI. If it is displayed in orange, the QuadCore is unable to connect to the NTP server.
Another note, the NTP server actually only triggers automatically on boot of the device. I usually recommend using a timer in ShowControl to periodically sync the time with the NTP server. To do this, first add a system startup action which starts a timer. Set it to 1 hour or something like that (If you set it too fast, the NTP server will probably reject) Next, add an action to the timer source, set the Triggerflank to stop, and add the task "TimeServer - Refresh". Also add the task "Timer - Restart" to restart your timer.
Another way would be to add the timeserver refresh to the scheduler.
Let me know if I can help,
Greetings,
Bootsy
