$sel:timezone:ScheduledAction', scheduledAction_timezone - The time zone used when referring to the date and time of a scheduled action, when the scheduled action uses an at or cron expression.

• Rate expressions - "rate(value unit)"
• Cron expressions - "cron(fields)"

At expressions are useful for one-time schedules. Cron expressions are useful for scheduled actions that run periodically at a specified date and time, and rate expressions are useful for scheduled actions that run at a regular interval.

At and cron expressions use Universal Coordinated Time (UTC) by default.

The cron format consists of six fields separated by white spaces: [Minutes] [Hours] [Day_of_Month] [Month] [Day_of_Week] [Year].

For rate expressions, value is a positive integer and unit is minute | minutes | hour | hours | day | days.
