You have a point Je-Je. What you are talking about sounds more like 'time of day', which really is quite arbitrary isn't it. Even time zones zig zag at times, and I learned recently that all of China defies physics and is all one time zone!... For some reason you can only guess.
And each year is actually 365.25 days roughly. So how old are you right now at this exact moment? You're clock is lying to you.
There seems to be the mathematical concept of 'time', but then there is the personal perception of 'time'. And even the mathematical concept is really just a measurement for the rate of change in the universe. If absolutely nothing moved, not even an electron, there would be no time.
I was thinking about how a spider views reality. How can it just sit there on a web for days on end without moving? It never get's bored and is probably not thinking about much at all and that is why. So 3 minutes, or 3 days, are irrelevant and it probably doesn't even notice.
Our rate of 'perceived' time is perhaps due to our 'speed of thought'. Or the '# of thoughts per second'.
I was also pondering why things appear to be 'fast' and 'slow'. It's always relative to us. We, and anything perceiving reality, will always feel like they are in the center and that is what comes natural. We don't notice a vine grow because it is so slow, and we can't see a hummingbird's wings flap because they are too fast. But with technology we can time-lapse that vine and truly see how magnificently alive it is, and capture that hummingbird in slow motion and see the intricate movements. These things and many more are happening all around us, every day, without us even knowing about them. We have just a narrow view of reality around us don't we?
Our own personal size is another reason. What is 'big' and 'small'? It too is always relative to us... and you can repeat that same paragraph above changing only a few words. Think about Earth compared to bacteria.If anyone was interested:https://www.youtube.com/watch?v=Fouo6GKGBIM(Hummingbirds in slow motion.)https://www.youtube.com/watch?v=dTljaIVseTc(Time-lapse of a vine growing.)
