@ranjith, I think that you may be confusing the difference between Unix/Linux cron <https://en.wikipedia.org/wiki/Cron> and the "cron<http://web2py.com/books/default/chapter/29/04/the-core?search=cron#Cron>" provided by web2py which are two different things. What @Marin is meaning is that you'd have the operating system's cron (or upstart or windows scheduler, nssm, whatever) kick off the scheduler process for you when the OS starts. I don't think that it is possible to have web2py's cron kick off the web2py scheduler.
