Being and time determine each other reciprocally, but in such a manner that neither can the former - Being - be addressed as something temporal nor can the latter - time - be addressed as a being.
Martin HeideggerWe name time when we say: every thing has its time. This means: everything which actually is, every being comes and goes at the right time and remains for a time during the time allotted to it. Every thing has its time.
Martin Heidegger
