Remarks

Returns the scheduled execution time of the most recent actual execution of this task. (If this method is invoked while task execution is in progress, the return value is the scheduled execution time of the ongoing task execution.)

This method is typically invoked from within a task's run method, to determine whether the current execution of the task is sufficiently timely to warrant performing the scheduled activity:

{@code
              public void run() {
                  if (System.currentTimeMillis() - scheduledExecutionTime() >=
                      MAX_TARDINESS)
                          return;  // Too late; skip this execution.
                  // Perform the task
              }
            }

This method is typically not used in conjunction with fixed-delay execution repeating tasks, as their scheduled execution times are allowed to drift over time, and so are not terribly significant.
