Can time flow backwards in a black hole?

We know that a black hole has escape velocity greater than the speed of light. And when something moves faster than speed of light then time flows backwards. As per my understanding time stops at the event horizon because escape velocity here is the speed of light. But what about inside of a black hole? Here the speed of the object thrown in is more than the speed of light.

So can time run backwards in a black hole?

Entropy decrease.

According to second law of thermodynamics entropy increases as time passes by. But inside a black hole entropy decreases (things become more structured) and thus thermodynamically time runs backward.

But how does the entropy decrease in a black hole?

My understanding.

If an object falls inside a black hole the mass of the black hole has increased slightly and so the area of event horizon increases. So when area is increased entropy decreases.

Am i right?

I have never heard of time flowing backwards except in science fiction.
