timeoutInMinutes

The length of time, in minutes, that CloudFormation waits for the nested stack to reach the CREATE_COMPLETE state. The default is no timeout. When CloudFormation detects that the nested stack has reached the CREATE_COMPLETE state, it marks the nested stack resource as CREATE_COMPLETE in the parent stack and resumes creating the parent stack. If the timeout period expires before the nested stack reaches CREATE_COMPLETE , CloudFormation marks the nested stack as failed and rolls back both the nested stack and parent stack. Updates aren't supported.
