Normally on a cron run, all cron tasks will be execute. This is not always necessary, because some of your cron tasks must i.e. only run once at day.
With this lightweight and simple module you can change the time of execution of each cron task. We recommend to run the main cron (URL) all 5min.
If you install the module, the timable cron table is empty. Run the cron and the cron table will be fill out with all the cron tasks that are used on your system. You can also deactivate cron tasks or force cron tasks to execute on the next cron run.
