Thank you for the patch and attention to detail. Unfortunately just adding to the enum does not result in successful detection. There's a need to modify code in src/detect/ScanI2CTwoWire.cpp as well.

Supporting PCF85063 would mean to migrate from the no longer maintained library lewisxhe/PCF8563_Library to lewisxhe/SensorLib which implements both RTC clocks with a unique interface. Then there's only work to be done in RTC.cpp besides removing/replacing all lewisxhe/PCF8563_Library in the platformio.ini files.

most likely comes from your GPS time

I have done the actual work of porting to SensorLib for PCF85063 support in #8061, this can be closed
