Choices, choices, choices
Change the script to:
#!/bin/bash
sudo ntpdate 0.pool.ntp.org
sudo hwclock --systohc
or
Change the script to:
#!/bin/bash
ntpdate 0.pool.ntp.org
hwclock --systohc
and
invoke it by `sudo <script_name>`
or
su
crontab -e
<insert line in crontab to have root run the script once every X>
exit
or
sudo chown root <script_name>
sudo chmod +x <script_name>
sudo chmod u+s <script_name>
The last one is what you asked for.
