Datability

""The datability of the 'now', the 'then', and the 'on that former occasion', reflects the ecstatical constitution of temporality, and is therefore essential for the time itself that has been expressed. The structure of the datability of the 'now', the 'then', and the 'on that former occasion', is evidence that these, stemming from temporaliy, are themselves time. The interpretative expressing of the 'now', the 'then', and the 'on that former occasion', is the most primordial way of assigning a time. In the ecstatical unity of temporality—which gets understood along with datability, but unthematically and without being recognizable as such—Dasein has already been disclosed to itself as Being-in-the-world, and entities withinthe-world have been discovered along with it; because of this, interpreted time has' already been given a dating in terms of those entities which are encountered in the disclosedness of the "there": "now that—the door slams"; "now that—my book is missing", and so forth."

Heidegger, B&T, pág. 461

"When Dasein is 'living along' in an everyday concernful manner, it just never understands itself as running along in a Continuously enduring sequence of pure 'nows'"

Idem, pág 462
