Most probably this has already been answered in other threads, but I can't find the exact solution.
I need to call a bash script via a php script which (bash) changes system time. I need to run that bash script as root while not changing apache permissions, i.e. php script called by user 'nobody' and the php script runs the script as root (sudoing is ok as I'm on ubuntu). As that will be called from a browser, I need to get rid of the password prompt
