before now. The exact time is not important. You CANNOT use the Present Perfect

with specific time expressions such as: yesterday, one year ago, last week, when I
was a child, when I lived in Japan, at that moment, that day, one day, etc. We CAN
use the Present Perfect with unspecific expressions such as: ever, never, once,
many times, several times, before, so far, already, yet, etc.
Examples:
 I have seen that movie twenty times.
 I think I have met him once before.
 There have been many earthquakes in California.
Passive Voice
Passive voice is used when the focus is on the action. It is not important or not
known, however, who or what is performing the action.
Example: My bike was stolen.
In the example above, the focus is on the fact that my bike was stolen. I do not
know, however, who did it.
Sometimes a statement in passive is more polite than active voice, as the
following example shows:
Example: A mistake was made.
In this case, I focus on the fact that a mistake was made, but I do not blame
anyone (e.g. You have made a mistake.).
