:?: Since the previous readers asked what do you mean regarding your question, I do not think it qualifies as being aware of the your 'point'.
Anyway, you could infer the meaning of time from what I have said about the future. It is a time or action that is away from the present and it did not happen yet, like the next millisecond, in an hour or must tomorrow as you have previously asked. You obviously have an idea of what the future is, and unless you ask the right question that can be answered, how can people understand what you mean. Do you require examples of word usage to express the future time? Like you have stated here:
PHP:
I have a hard time in seeing what is the present time and what is the future time.
Must tomorrow is a future time?
What about next hour?
What about next minute?
What about next second?
Are they all the future time?
All of these are future time, because they have not come to be yet. Time is moving backwards while you can stand in place and wait for this time to come or move towards it. Pretend you're on a highway facing North and all the cars ( imagine the cars are the time) are moving South. You stand in place and await a car that is 10KM away, eventually the car will come to you. When you meet, that will be the present and when it passes you by, that will be the past. Or, that car is in place at 10KM away and you are moving towards it, you are moving in the present, you exist within that time, and that car is in the future, because you have not met yet. Once you meet it will become the present time and if you continue on that road and pass it, it instantly becomes the past. It depends on how you view the action that is supposed to happen. You can await the 'specific' millisecond which can be the next one after the one that is in the present time or it may be a minute away. You can refer to next week, which the whole week will be the future time that you are awaiting because something will keep happening during that week which will count as the present as soon as you are within that week. You must specify if the time you await is small or big like a minute or an hour. Everything that you await to happen is the future, it does not matter whether it is whitin the present day or the present week.
PHP:
If "today" is present time, how can it be that "in two hours" is the future time? Do you mean the future time is within the present time? How can it be possible that I am within "today", but outside "in two hours"? Is "in two hours" outside "today"? I don't understand.
Or do you mean this "in two hours" sometimes won't take place? May you elaborate on this? Thank you very much.
In previous post I have tried to explain that. Today is present time, it refers to the 'whole' day in general, you wanted this time to come, those 24 hours, and they did, so it is the present. If you are in time at 1400 hours and you are awating a delivery at 1600 then that is the future, because you are refering to a different time, something that did not happen yet. The day 'today' happened and it is the present, delivery did not come to be yet so it is the future.
I was mistaken as to the answer that you have required, and the way I understand time, I have tried to put into words. If I still have not answered a part of your question and have been blubbing senslessly then I apologize for taking your time while reading. "While you are reading it is the present, the milliseconds and minutes can go by, they are not relevant. It's like you're on a highway and reached the car, you look at it, inspect it, when you continue on, that becomes the past and whatever lies ahead is future. When you finish reading it will become the past and when you go to post your own reply which did not happen yet, it is the future." You have to look at the time and realize the concept, figuratively apeaking. The right answer requires the right question, I have tried and learned. I am only human.
