A Workflow Execution Timeout is the maximum time that a Workflow Execution can be executing (have an Open status) including retries and any usage of Continue As New.
The default value is ∞ (infinite). If this timeout is reached, the Workflow Execution changes to a Timed Out status. This timeout is different from the Workflow Run Timeout. This timeout is most commonly used for stopping the execution of a Temporal Cron Job after a certain amount of time has passed.
