You can't say present perfect. A verb is either present or perfect.

I disagree. The present perfect tense is a very common tense in the English language.
"I have finished," "we have gone," and "John has eaten" are all examples of the present perfect tense. It is formed by using a present tense conjugation of the helping verb (auxiliary verb) have and the past participle.

The past perfect tense uses the past tense conjugation of the auxiliary and the past participle. For example:
I had finished
we had gone
John had eaten

The future perfect is similarly formed:
I will have finished
we will have gone
John will have eaten

The present perfect passive just throws been to the mix.
For example:
We have been given
Jill has been seen

The past perfect passive:
You had been given
Jack had been seen

The future perfect passive:
I will have been given
John will have been seen
