Tense Confusion

Confusion with tenses

Does "Has been" imply that the action is finished ... or is it used for passive structures...

and .. could you please explain when to use .. "having", and "having been" ??

thanks

The auxiliary or "helping" verbs are confusing for a lot of people. Take this example:

"The dog has been walked."
The "been" auxiliary verb makes the voice passive: some unnamed person walked the dog.
The "has" auxiliary verb makes the tense present perfect: In this case, the dog may not still be walking, but it is still true that the walk occurred (presumably in the recent past).

As for the "having" vs. "having been" question, it might help us to see the example you have in mind. "Having" can be used either as an auxiliary verb or as a main verb. You can make up an example, if that works for you.
