Detailed Description

This work, "Cheetah - https://www.cheetahwsb.com", is a derivative of "Dolphin Pro V7.4.2" by BoonEx Pty Limited - https://www.boonex.com/, used under CC-BY. "Cheetah" is licensed under CC-BY by Dean J. Bassett Jr. CC-BY License - http://creativecommons.org/licenses/by/3.0/ ChWsbCron is parent class for all Cheetah cron jobs, except the cases when the code is evaluated directly.

periodic/cron.php file is used for cron jobs. It is started every minute and runs Cheetah cron jobs. The file runs jobs at regular intervals, the jobs are listed in sys_cron_jobs table.

Fields shark_cron_jobs table: id - key for the table name - job name to be executed time - format of entries are five fields of numbers specifying the minute, hour, day of the month, month and day of the week that a task must be executed.

class - class name which will run file - path to class file eval - source code which will run

The time numbers can be given as a comma separated list of simple numbers, ranges("2-5" is the same as "2,3,4,5"). A single "*" can be used in a field to indicate all valid numbers in that field, so it translates to "always". If a given time is valid in all five fields then a module function is executed. Here are a few examples that illustrate the possibilities:

will run at 16:10: 10 16 will run at 2:00 on saturday: 0 2 * * 6 will run at midnight on new years: 0 0 1 1 0 will run every 15 minutes: *\/15 will run at 22:00 on work weekdays: 0 22 * * 1-5 will run each 23 minutes, 2:00, 4:00 ..., everyday 23 0-23/2

Example add new cron job:

Create new class inherited from "ChWsbCron" and add method "processing"

class ChWsbCronMy extends ChWsbCron {
```
function processing()
{
    // insert code
}
```
}
Add record in sys_cron_jobs table
