Both locations should work. If you change /etc/init.d/hwclock.sh then
you have to take care whenever the "util-linux" package is updated. The
change will be noticed and you will be asked if you want to keep your
version or install the package maintainer's new version. It is probably
better to install the new version and then change the "HWCLOCKPARS="
line again in the new file.
Using /etc/default/rcS avoids this issue. If you want to understand how
it works you have to look a bit further in hwclock.sh and you will see
. /etc/default/rcS
This is the short way of writing "source /etc/default/rcS". At this
point /etc/default/rcS is read and all commands in it are executed as if
they had been included in hwclock.sh. This makes all the variable
assignments in rcS available to hwclock.sh. A number of the other
scripts in /etc/init.d also use /etc/default/rcS in that way. So this is
a more centralized mechanism and it saves you the trouble of having to
remember which init scripts you changed.

Sure, no problem.
