For the most part I don't concern myself with clock time, but on those rare occasions when I have reason to consider it, I prefer my analog pocket watch.
I consider clock time to be an artificial construct to which much of human society has assigned too much importance.
in reply to I prefer this kind of clock or watch:
I'll do what I can, though, to minimize the run time of an application out of respect for the user and the finite duration of his or her time on Earth. That's the measure of time that matters.
