My DS3231 loses a couple of secs/day. Research revealed the existence of an 'AgingRegister'. I'm not a C/C++ programmer, just a continually learning 'Arduino' progarmmer and so far I've not learned how to use it after reading many threads and browsing several DS3231 libraries.
I'd guess many users at a similar skill level would benefit from an Example sketch or independent function that allowed simple adustment of this register. Trial and error could then restore tolerable accuracy.
