The ability to run scheduled jobs makes administering the web site more usable, as administrators do not have to manually start jobs.

It can be used to control the execution of daily, weekly and monthly jobs (or anything with a period measured in seconds). The aggregator module periodically updates feeds using cron.  Ping periodically notifies services of new content on your site.  Search periodically indexes the content on your site.   Automating tasks is one of the best ways to keep a system running smoothly, and if most of your administration does not require your direct involvement, cron is an ideal solution.') . '</p>';
