This is a Present Tense which is wholly in the past.

When presenting this information to language learners, it is presented as a present tense. Many people logically categorize this in the past tense however. In the lens of grammar in general (and not english grammar in particular), English has only two tenses: past and non-past. Present Perfect is clearly not non-past tense.

the Present Perfect	The boy has seen the car. (Emphasis is on the present state of the boy, resulting from the fact that he saw the car.)
the During sense of the Present Perfect	I have left Argentina for now. I have had a cold for two weeks. The earth has had humans on it for four million years.
