Nasor,
What do you mean by this? Time can be quantified and expressed in terms of units. Is that not measuring time?
That's how we define time into our perception. The brain works this way. It slice everything into small pieces in order to be able to organize it. However, by doing so, a lot of information is actually lost or distorted.
Time
itself is the time without someone perceiving it. Imagine if you wouldn't exist. How would be time then? Would time still exist? It would exist for others, but not for you. That's what I talked in this thread. Everyone perceives time in a different way, eventhough to measure time we still use the same units. As we are subjected to time, we tend to measure it.
So time for us is measurable. Time is the object, we are the subjects. But time itself is unmeasurable since there is no subject and object.
It is true that our perception of time is not always accurate. This is why we use devices and processes to measure time that are not dependant on our perception. Like clocks.
It is still our perception. If you and a chinese guy look to a clock at the same time, it is very likely that you will see different numbers in them. It is still defined by
your perception opposed to mine.
Yes, when the sun shines on one half of the earth it will be dark on the other half. I don't see how this is relevant to the discussion.
Again, the time perceived here will be different then the time perceived in China. Besides, the present is always changing its position in relation to the past and future, which also creates an illusion that we are always walking towards a future and away from the past. The Truth is that there is only a present, a present continuous.
It is all a matter of subject and object. If you take into account the subject and object, time can be measured (although not perfectly measured as the distances increase). If you don't take subject and object into account, than all that you have is an
everlasting present.
