If set, specifies the default maximum duration for executions of this workflow type. You can override this default when starting an execution through the StartWorkflowExecution Action or StartChildWorkflowExecutionDecision. The duration is specified in seconds. The valid values are integers greater than or equal to 0. Unlike some of the other timeout parameters in Amazon SWF, you cannot specify a value of "NONE" for defaultExecutionStartToCloseTimeout; there is a one-year max limit on the time that a workflow execution can run. Exceeding this limit will always cause the workflow execution to time out.
