## Description

Certain requests for Usage Records can only be made with StartTime and EndTime parameters that align to a UTC hour cutoff (e.g. "2021-07-15T04:00:00Z").

### Possible Causes

- This happens if you request Usage Records with StartTime or EndTime parameters that do not fall on an hour cutoff for certain UsageRecord requests.

### Possible Solutions

- Adjust your StartTime or EndTime parameters so that they are on a UTC hour cutoff (e.g. "2021-07-15T04:00:00Z").
