Time as right and wrong time has the character of significance, the character that characterizes the world as world in general. It is for this reason that we call the time with which we reckon, which we leave for ourselves, world-time. This does not mean that the time we read from the clock is something extant like intraworldly things. We know, of course, that the world is not an extant entity, not nature, but that which first makes possible the uncoveredness of nature. It is therefore also inappropriate, as frequently happens, to call this time nature-time or natural time. There is no nature-time, since all time belongs essentially to the Dasein. But there is indeed a world-time.
-- Heidegger, Basic Problems of Phenomenology
