The various tenses indicate times when actions occur.  How those verb tenses are formed clue readers into those different time frames.

1. Simple past tense (example: walked) tells us that an action is over-and-done-with.
2. Present perfect tense (example: has walked or have walked) tells us that the action started in the past and has probably continued up to the present moment.
3. Past perfect tense (example: had walked) tells us that the action took place prior to some other action in the past.
