startTime

A timestamp that indicates the start time of the requested finding history.

If you provide values for both StartTime and EndTime, Security Hub returns finding history for the specified time period. If you provide a value for StartTime but not for EndTime, Security Hub returns finding history from the StartTime to the time at which the API is called. If you provide a value for EndTime but not for StartTime, Security Hub returns finding history from the CreatedAt timestamp of the finding to the EndTime. If you provide neither StartTime nor EndTime, Security Hub returns finding history from the CreatedAt timestamp of the finding to the time at which the API is called. In all of these scenarios, the response is limited to 100 results, and the maximum time period is limited to 90 days.
