In German there is one tense that is more or less equivalent called Futur II or Futur exakt (also called Vorzukunft which literally translates to Prefuture). It is used to describe events which will be past in the future.
It is also not that similar, since PPT is speaking about events in the future in past tense as if they have already happened and Future Perfect/Futur II uses "will": "I will have finished my homework by tomorrow."
But you seemto contradict yourself; you say that PPT is FP, and then say that "it is not that similar"; they can't be the same thing, and yet dissimilar.
