I'd rather lean towards the timekeeping code doing that. The RTC

Heh, touche'!  :)

subsystem doesn't know which RTC has to be used.

Though the RTC layer *is* the one that tracks which RTC is used, via
the logic in drivers/rtc/class.c, and the timekeeping core already has
adjtimex for timekeeping corrections, so if we're correcting
underlying RTCs it seems such tuning would best be done in the RTC
layer.

Though how the persistent_clock interface ties into such corrections
would be a separate thing.

Might be the final trigger to get rid of that leftover from the last
millenium?
