Full Idea
We can talk of 'moments of time' as abstract objects. This will be attractive to the presentist. As possible worlds give an economical theory of modal talk, so 'times' gives us a theory for temporal talk.
Gist of Idea
Presentists can talk of 'times', with no more commitment than modalists have to possible worlds
