Identifies the date and time that an in progress on-demand rotation was initiated.

The KMS API follows an <a
href="https://docs.aws.amazon.com/kms/latest/developerguide/programming-eventual-consistency.html">eventual
consistency</a> model due to the distributed nature of the system. As a result, there might be a slight delay
between initiating on-demand key rotation and the rotation's completion. Once the on-demand rotation is complete,
use <a>ListKeyRotations</a> to view the details of the on-demand rotation.
