public int getWindowEnd() {
      return windowEnd;
    }
ExecutionWindow represents a Job trigger that becomes eligible once the current elapsed time
exceeds the scheduled time + the {@code windowStart} value. The scheduler backend is encouraged
to use the windowEnd value as a signal that the job should be run, but this is not an enforced
behavior.
