The interval period and timezone to apply to returned metrics.

<code>IntervalPeriod</code>: An aggregated grouping applied to request metrics. Valid <code>IntervalPeriod</code>
values are: <code>FIFTEEN_MIN</code> | <code>THIRTY_MIN</code> | <code>HOUR</code> | <code>DAY</code> |
<code>WEEK</code> | <code>TOTAL</code>.
</p>
<p>
For example, if <code>IntervalPeriod</code> is selected <code>THIRTY_MIN</code>, <code>StartTime</code> and
<code>EndTime</code> differs by 1 day, then Amazon Connect returns 48 results in the response. Each result is
aggregated by the THIRTY_MIN period. By default Amazon Connect aggregates results based on the <code>TOTAL</code>
interval period.

The following list describes restrictions on <code>StartTime</code> and <code>EndTime</code> based on which
<code>IntervalPeriod</code> is requested.
