is
True if this process ended because it exceeded its maximum allowed execution time. This is a recorded-outcome accessor: the live wall-clock comparison (elapsed since beginExecutionTime vs. maximumAllowedExecutionTime) is performed between steps while the process runs, and the EndingStatus.EXCEEDED_EXECUTION_TIME outcome is recorded when it trips; this property reads that outcome back.
Return
true if the process ended via EXCEEDED_EXECUTION_TIME
