Student or Learner
I'm learning English, and i'm confused, can anyone helps me?
in present perfect i can use it with unspecified time before now, but also i can use it with change over time sentences !!
, and the change over time sentences has refers to a specified time (Ex: you have grown since the last time i saw you. here the last time is a specified time !!), so that i'm confused.

First thanks for your replay.
but even if i say (i last saw you) it's also a specified time that means the last time i met him, and it's a specified time.
The specified time refers to 'saw/met', which are the simple past instead of the present perfect.
Not a teacher.
No specified time is in the first clause where the present perfect is used.
The specified time is in the second clause where the simple past is used.
What is your confusion?
Not a teacher.
You've made a few statements and left it to us to work out what it is you want to know. Since that hasn't seemed to work, I suggested you formulate a question. Doing so might even clarify the answer for you.
You can say "I ate at that restaurant last year."
You can say "I have eaten at that restaurant" with no time given.
You cannot grammatically say "I have eaten at the restaurant Sunday."
But you can use say "I have eaten" SINCE a specific point in time -- at some indefinite point of time between now and that time in the past.
I have eaten there since they changed owners and it wasn't as good as before.
I have not eaten there since last year.
This is even more true for progressive verbs, like "to grow" (which don't happen on one night, like eating in a restaurant).
You can't say "Your grew so much on Saturday." (Not with the same meaning - I guess you could have had something happen that led to tremendous emotional growth.) You need a period of time for the growth to have taken place.
You have grown so much since then. -- Over the period of time from now until I last saw you, this has happened gradually.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
