ExecutionStartToCloseTimeout Property
AmazonAmazon.SimpleWorkflow.ModelStartWorkflowExecutionRequestExecutionStartToCloseTimeout Did this page help you?   Yes   No    Tell us about it...
The total duration for this workflow execution. This overrides the defaultExecutionStartToCloseTimeout specified when registering the workflow type. The duration is specified in seconds. The valid values are integers greater than or equal to 0. Exceeding this limit will cause the workflow execution to time out. Unlike some of the other timeout parameters in Amazon SWF, you cannot specify a value of "NONE" for this timeout; there is a one-year max limit on the time that a workflow execution can run.
Note:
An execution start-to-close timeout must be specified either through this parameter or as a default when the workflow type is registered. If neither this parameter nor a default execution start-to-close timeout is specified, a fault is returned.
