An RTC wrong by more than an hour, e.g. two months ago, if I have an internet connection chrony sets the system clock to the correct date/time. If I don't have an internet connection, I'm relegated to a system time based on the wrong RTC, which seems grossly broken to me. 

Well, if your clock is wrong, and you don't have an Internet connection,
what else can be done?  I don't understand your complaint here.

> c. Windows and OS X do not behave this way - almost immediately upon getting correct time from an internet source, those OS's update the RTC to the correct time.

Do they do that in a secure fashion?  Jumping the clock also has
consequences.
