        #     must be specified, must be earlier than the end time, and should be
        #     no older than the data retention period for the metric.
        #   * Writes: A closed time interval. It extends from the start time to the end
        #   time,
        #     and includes both: `[startTime, endTime]`. Valid time intervals

        #     time, and the end time must not be more than 25 hours in the past or more
        #     than five minutes in the future.

        #       no value is specified, the start time defaults to the value of the
        #       end time, and the interval represents a single point in time. If both
        #       start and end times are specified, they must be identical. Such an
        #       interval is valid only for `GAUGE` metrics, which are point-in-time
        #       measurements. The end time of a new interval must be at least a
        #       millisecond after the end time of the previous interval.

        #       non-zero interval, with subsequent points specifying contiguous and
        #       non-overlapping intervals. For `DELTA` metrics, the start time of
        #       the next interval must be at least a millisecond after the end time
        #       of the previous interval.
        #     * For `CUMULATIVE` metrics, the start time and end time must specify a
        #       non-zero interval, with subsequent points specifying the same
        #       start time and increasing end times, until an event resets the
        #       cumulative value to zero and sets a new start time for the following

        #       end time of the previous interval because intervals are closed. If the
        #       start time of a new interval is the same as the end time of the

        # `alignment_period` time intervals. This process takes _all_ of the data
        # points in an alignment period, applies a mathematical transformation such as
        # averaging, minimum, maximum, delta, etc., and converts them into a single
        # data point per period.

        # Reduction is when the aligned and transformed time series can optionally be
