Anyway, some RTCs had a century register and some didn't. wiki.osdev.org/CMOS#Century_Re

Some RTCs with a century register suffered from a bug where it wouldn't actually be incremented. dell.com/community/en/conversa 🤦‍♂️

Not sure about my 486. It was powered on and running Linux when the century rolled over. If the RTC did have an incrementation bug, it would've been corrected automatically; resetting the RTC was part of the shutdown sequence.
