Don't use the past perfect unless there is another verb in the past tense in the same sentence.
If we are speaking of an action just finished, we must use the present perfect instead of the simple past tense. For example, immediately after the clock strikes, we shouldn't say The clock struck, but The clock has struck.
Use the present perfect (and not the simple present) for an action begun in the past and continuing into the present. I've been at this school two years means I'm still here.
