Almost agree :)

That part is correct, but if CPU is down, there is no code to execute,
therefore need some unit to calc that interrupts :) and unfortunately that
unit called also "real-time clock" you can also find chip for example
PCF8583 with that function, which is working from lithium battery or other
energy source which is also called "Real-time clock":).

I think your your terminology is off.
A real-time clock is a high precision clock that periodically triggers
a high priority interrupt to ensure some code is executed exactly at
This is separate from hwclock which is just a time keeper and does not
create interrupts. and only provides to the second information.
