The optional default maximum duration, specified when registering the workflow type, that a decision task for executions of this workflow type might take before returning completion or failure. If the task does not close in the specified time then the task is automatically timed out and rescheduled. If the decider eventually reports a completion or failure, it is ignored. This default can be overridden when starting a workflow execution using the StartWorkflowExecution action or the StartChildWorkflowExecutionDecision. The valid values are integers greater than or equal to 0. An integer value can be used to specify the duration in seconds while NONE can be used to specify unlimited duration.
