  Finally, one might wonder whether the ‘realist Heidegger’ can live with the account of temporality given in Being and Time. If temporality is the a priori condition for us to encounter entities as equipment, and if, in the relevant sense, the unfolding of time coincides with the unfolding of Dasein (Dasein, as temporality, temporalizes; see above), then equipmental entities will be intelligible to us only in (what we might call) Dasein-time, the time that we ourselves are. Now, we have seen previously that nature is often encountered as equipment, which means that natural equipment will be intelligible to us only in Dasein-time. But what about nature in a non-equipmental form—nature (as one might surely be tempted to say) as it is in itself? One might try to argue that those encounters with nature that reveal nature as it is in itself are precisely those encounters that reveal nature as present-at-hand, and that to reveal nature as present-at-hand is, in part, to reveal nature within present-at-hand time (e.g., clock time), a time which is, in the relevant sense, independent of Dasein. Unfortunately there's a snag with this story (and thus for the attempt to see Heidegger as a realist). Heidegger claims that presence-at-hand (as revealed by theoretical reflection) is subject to the same Dasein-dependent temporality as readiness-to-hand:
