        # Creates a scheduled scaling action for a Auto Scaling group. If you
        # leave a parameter unspecified, the corresponding value remains
        # unchanged in the affected Auto Scaling group.
        #
        # ==== Parameters
        # * auto_scaling_group_name<~String> - The name or ARN of the Auto
        #   Scaling Group.
        # * scheduled_action_name<~String> - Name of this scaling action.
        # * time<~Datetime> - The time for this action to start (deprecated:
        #   use StartTime, EndTime and Recurrence).
        # * options<~Hash>:
        #   * 'DesiredCapacity'<~Integer> - The number of EC2 instances that
        #     should be running in this group.
        #   * 'EndTime'<~DateTime> - The time for this action to end.
        #   * 'MaxSize'<~Integer> - The maximum size for the Auto Scaling
        #     group.
        #   * 'MinSize'<~Integer> - The minimum size for the Auto Scaling
        #     group.
        #   * 'Recurrence'<~String> - The time when recurring future actions
        #     will start. Start time is specified by the user following the
        #     Unix cron syntax format. When StartTime and EndTime are specified
        #     with Recurrence, they form the boundaries of when the recurring
        #     action will start and stop.
        #   * 'StartTime'<~DateTime> - The time for this action to start
        #
        # ==== Returns
        # * response<~Excon::Response>:
        #   * body<~Hash>:
        #     * 'ResponseMetadata'<~Hash>:
        #       * 'RequestId'<~String> - Id of request
        #
