Using the UNIX cron grammar

The scheduling policy for jobs is based on the UNIX cron grammar. The table below shows you the format in use to type scheduling parameters:

Format	Meaning
*	In the Unix cron grammar, "all possible values" is represented by an asterisk. On the General tab of the Rating Session Job and Cleaning Database Job windows, "all possible values" is represented by: - An empty field in the Seconds, Minutes, Hours, or Days fields - All the check boxes cleared in the Days of weeks, or Months areas
n	A single integer is used to match that exact value
m-n	Two integers separated by a dash are used to match any value within the range
m,n	A list including integers that are separated by commas and used to match a value

Time units are expressed in second, minute, hour or day.

Notes:

An empty field means "every". For example, if the Seconds field is empty, this means "every second".
In the Days of weeks and Months areas, all the check boxes cleared means “every day” in the Days of weeks area and “every month” in the Months area.
