Thanks for the comments @fhueske. I will pay more attention to the coding
style.
Actually, there are many ways to implement this feature. At first, I planed
to override the `processWatermark` method in the sub-class. However, the
instance variable `timeServiceManager` needed is declared as private. I'm not
sure if this can be changed.
