User blog comment:Neko Neko no Mi Model: Russian Blue/The potential merits of a Time-Time fruit, particularly one held by an Admiral/@comment-33000331-20180615184519

If time-travel were to be introduced then maybe:

A) Important Historical Events in first person. (The Void Century, Roger's Era, etc.)

B) Younger versions of dead or living characters.

C) Other Devil Fruit eaters of the same Devil fruits

D) The grandfather paradox.

E) The future.

But honestly I would like it if Greenbull really was a greenbull. That would complete the Devil Fruit Trio(Logia, Paramecia, Zoan). However if he is time then the combo would be Light, Gravity, and Time. That trio is not as solid as the devil fruit trio.
