	// The expression that defines when the schedule runs. The following formats are
	// supported.
	//   - at expression - at(yyyy-mm-ddThh:mm:ss)
	//   - rate expression - rate(unit value)
	//   - cron expression - cron(fields)
	// You can use at expressions to create one-time schedules that invoke a target
	// once, at the time and in the time zone, that you specify. You can use rate and
	// cron expressions to create recurring schedules. Rate-based schedules are useful
	// when you want to invoke a target at regular intervals, such as every 15 minutes
	// or every five days. Cron-based schedules are useful when you want to invoke a
	// target periodically at a specific time, such as at 8:00 am (UTC+0) every 1st day
	// of the month. A cron expression consists of six fields separated by white
	// spaces: (minutes hours day_of_month month day_of_week year) . A rate expression
	// consists of a value as a positive integer, and a unit with the following
	// options: minute | minutes | hour | hours | day | days For more information and
	// examples, see Schedule types on EventBridge Scheduler (https://docs.aws.amazon.com/scheduler/latest/UserGuide/schedule-types.html)
