  1. Sorry , was not able to try this until now! So I think I was supposed to change following lines in .sh file EXTERNAL_RTC="rtc0" INTERNAL_RTC="rtc" [I put rtc0 and rtc in there] and I copied the .sh file to /etc/conf.d and ran it using sudo but I get only this output Current date on RTC (/dev/rtc0): And nothing else. Thanks for helping me with this , but its still not working.
