The Cron Manager is the program used to install, deinstall or list scheduled commands.
The Cron Manager is part of the main Server Administration control panel, and can be activated for each site using the Site Manager.
Each line has five time and date fields, followed by a command. Commands are executed by cron when the minute, hour, and month of year fields match the current time, and when at least one of the two day fields (day of month, or day of week) match the current time.
