days

Indicates the number of days after creation when objects are transitioned to the specified storage class. If the specified storage class is INTELLIGENT_TIERING, GLACIER_IR, GLACIER, or DEEP_ARCHIVE, valid values are 0 or positive integers. If the specified storage class is STANDARD_IA or ONEZONE_IA, valid values are positive integers greater than 30. Be aware that some storage classes have a minimum storage duration and that you're charged for transitioning objects before their minimum storage duration. For more information, see Constraints and considerations for transitions in the Amazon S3 User Guide.
