<!--

<!--
* The frequency settings take similar values as used in
* crontab entries
* E.g., "1", "2-3", "2-3,5,6", "*/2", "1-6/3", "*", etc.
* ("*" is assumed for any values that are omitted)
*
* The primary difference with crontab entries is that the task
* may not be executed at the exact specified time. E.g., if a
* task is set to execute at minute 0 of every hour, it will be
* executed if it has been more than one hour since the task
* was last run, regardless of the minute at the time the
* script is actually executed.
*
* minute: 0-59
* hour: 0-23
* day: 1-31
* month: 1-12
* dayofweek: 0-6 (Sunday-Saturday)
