  Second, McTaggart accepts that the doctrine of temporal parts is well-founded: if time is real, then objects have temporal parts corresponding to each moment at which they exist. If time is unreal, then objects have parts corresponding to each node in the real C-series that they occupy. This view is articulated in several places in both volumes of the Nature of Existence, and it plays a minor argumentative role in section 163 of volume I. Interestingly, McTaggart does not explicitly argue for the doctrine, but rather seems to think that the doctrine of temporal parts will be ‘generally admitted’. (See the second volume of the Nature of Existence, section 412.)
