I'll bet an interesting history lurks behind such a seemingly simple topic

Depends a bit on what you mean by "real time
clock".
For many decades "real time clock" has meant some sort of repeatable
time event, eg. 60Hz line, 1mS, usually in the form of an interrupt. I'm
certain terminology has varied all over the place (never mind
non-English) but reasonably universally this is the intent.
That other thing, electronic or otherwise, that knows about Julian dates
and tea time and all that is called a "clock/calendar" or something like
that.
