JPrc Cron is a Joomla package (a component and a plugin) for Cron Jobs Management and Scheduling.
Its purpose is to simulate cron jobs through Joomla front end interface at preset periods of time for users who either don't have access to the server crontab/cPanel or don't want to use it for any purpose.
It is launched at the preset time only if your site gets visits in place. Each time a user or spider accesses your public site you will have the cron running. Eg if you set 3:00am, it might run 3:10am (according your site traffic).
If you need a solution to run, even if there's no visit, you need a server side solution to run within regular and fixed periods of time.
*** This software is a based in venerable JCron, updated to the new J1.6/1.7. ***
Download the last version of the module and install it using the default install procedure of Joomla!.
Note: to execute the cron jobs, it uses the PHP exec() function, so your provider must have it enabled to run a command. In the other hand, you can also work only calling Urls.
Please, remember to enable the plugin. After that, you can create your first Job.
