# 83601: Request StartTime and/or EndTime must be aligned to UTC day boundaries

Log Type: APPLICATION

Log Level: ERROR

## Description

Certain requests for Usage Records can only be made with StartTime and EndTime parameters that align to midnight UTC (e.g. "2021-07-15T00:00:00Z").

### Possible causes

* This happens if you request Usage Records with StartTime or EndTime parameters that do not fall on a day cutoff (i.e. midnight UTC) for certain UsageRecord requests.

### Possible solutions

* Adjust your StartTime or EndTime parameters so that they are at midnight UTC (e.g. "2021-07-15T00:00:00Z").
