• RTC drift

The drift of intern RTC is enormous. On CANRec its running way to fast (LSE not even enabled? and not used by RTC?).
The calibration is capable to adjust several seconds per month, not per day.
Not sure if an per-device config is even necessary or if it is an per type thing.

CANRec can request time values periodically from all devices. It can only compare it to the own clock, so this is not usefull.
Cordyceps can analyse this. It has a "real" working RTC form the computer.
