Decisive being is a form of temporal being that takes into the bounds set by intention the points in time marking the beginning and the end what somewhat is within.  Such bounds are set as if by principle for consciousness could mark the beginning and the end only by its own commencing and ending which it cannot know.  This is deducible from the analytical awareness of what is the present.  

Being in the present is also in principle.  We know the present to be equivalent to the now in terms of temporaneity.  This moment in time is an abstraction practically applicable and further is with the markers of the hands of the clock or the counter of the digital watch.  The clock holds true as in in common the present moment and allows the accounting of all the previous moments thus marked and allows marking of moments of the future projected.  So too the seasons, calendar, dates, months, weeks, and days.  

When the act to take in the particulars selected for consideration and deliberation by intention knows the principle of beginning and end to a duration, recognition occurs for the abstract nature of the principle for consciousness in one faculty represents and in another cognizes so therefore whichever somewhat selected could be from some such moment at least in the past and the present.  What object or percept were possible from some future, in that the future is too a principle, could be represented or cognized or by some other faculty grasped is of a seemingly unknowable nature.  When what somewhats were rediscovered after the percept received earlier, whether considered objective or else, decisive being is once more called upon to act with the decision here concerning whether to remember the percept and what decision was by intention made, as well as the more obvious how to apprehend the current occurrence, or the vulgar, in the Heideggerian sense, grasp of just what about this as if such were a non-event.

To revel in such an encounter should be only human, but what other horizons lie awaiting.  The terms with which to grasp time should be orderly for the records show that the technology of notion was conceived slowly and historically so that even historical consciousness began to emerge for the common mind.  Orderliness with which to comprehend, or rather to apprehend being in time, could be with presupposition of how time is to be grasped in sequence, first in practicality, then in principle, then in consciousness, then and only then further.  For the continuum in which we found ourselves was only wild; only with the crafting of the keeping of measures over the continua do the actions in such as common time become possible.  Without establishing that such is the natural order we have found as humans, to proceed forward in time together, whatever time may be, the techniques and technology of time keeping may be undermined and progress arrested, worse yet, reversed, by no pun.
