We know Maz is centuries old. So one would assume for her that an "age" is a fairly long period of time (at least on the scale of a hundred years or more).
So when she says, at about the 1:11:50 mark of the theatrical version of The Force Awakens, that she has had Anakin/Luke Skywalker's lightsaber "for ages" (a low quality clip of the scene can be found here), how can this time frame be accurate, since the construction of the item occurred less than 100 years earlier and its last known time of possession was only about 30 years previous?
Is an "age" in her time frame or language really equal to a lesser number (like a year)? Is there some possibility of time travel involved in the Star Wars universe, such that she really did acquire it "ages" ago with respect to her own, literal lifetime? How does one make "in-universe" sense of the statement?
