-You can also specify `Task.StartTime` to be in the future, therefore delaying the execution of the function until the specified time.
+### With start time and end time
+You can also specify `StartTime` and/or `EndTime` to time bound the task's execution. `StartTime` allows the scheduler to wait until the specified time to execute the function, while `EndTime` is used with interval or CRON to end the execution of the task after a certain period of time passes.
