 There is an ambiguity in this last quote, however, that we must note. Did Gödel think that the layers of now come into existence (as what is to be becomes what is now) and then immediately cease to exist (as what is now becomes what once was), which is the presentist metaphysics of time? Or did he think that the layers of now come into existence and forever stay in existence, as the possibilist picture maintains? If one’s basic ontology consists of the sort of events characterized above and often invoked in discussions of time, (idealized) instantaneous happenings, then the presentist picture seems inevitable.
