A verb has different forms by which it can indicate the time of action. These forms are called tenses ("times").
I see you. (Present tense, marking present action).
I saw you. (Past tense, or preterit, marking past action).
I shall see you. (Future tense, marking future action).
In order to show the completeness of an action at the time of speaking, we use perfect tenses.
Now I have caught you. (Present perfect, or perfect, marking action completed at the present time).
We spoke to him after he had spoken to us. (Past perfect, or pluperfect, marking action completed in past time).
We shall have climbed the mountain before you reach the spring. (Future perfect, marking action that will be completed in future time).
Of the six tense forms only two are simple, the present and the past. The others are combinations of the auxiliary verbs (will, shall, have, be, or do) with infinitives and participles.
