Is it possible to Install Raspberrt Pi(rate)Box without timesave if I use a Real Time Clock (RTC) like DS3231?

Hi all...
I've successfully set-up as a first thing before starting the set-up steps a DS3231 RTC using the tutorial here .
Then I want to skip completely the second step of set-up, the one about timesave since I think is not needed anymore
Is it ok to run instead of

Language: PHP
sudo /opt/piratebox/bin/timesave.sh /opt/piratebox/conf/piratebox.conf install

this:

Language: PHP
/opt/piratebox/bin/install_piratebox.sh /opt/piratebox/conf/piratebox.conf part2

and then continue with the other steps?

Thanks!
