The last scheduling option is Cron. Cron lets you schedule syncs on arbitrary schedules such as every 3 hours, or only week days. Census accepts standard Cron definitions up to minute granularity (second-level granularity cron definitions are not supported). A Cron schedule is specified by a series of five values, separated by spaces. In order, the values are Minute-of-hour, hours-of-day, Days-of-month, Months-of-year, and Day-of-week. The timezone is UTC.
