duration

The length of the rotation window in hours, for example 3h for a three hour window. Secrets Manager rotates your secret at any time during this window. The window must not extend into the next rotation window or the next UTC day. The window starts according to the ScheduleExpression. If you don't specify a Duration, for a ScheduleExpression in hours, the window automatically closes after one hour. For a ScheduleExpression in days, the window automatically closes at the end of the UTC day. For more information, including examples, see Schedule expressions in Secrets Manager rotation in the Secrets Manager Users Guide.
