Time

What is time?
It's hard to define or feel it as an actual existence.

There are some opinions about time.

1. The time exists as physical movement, and it goes one way with the same speed.
Since it follows physics, it CAN reverse backwards.

2. Time increase, following the entropy of physical phenomenon. Thus, time is relative existence.

3. Time is a parameter of a phenomenon happened in a space. Thus, time can't be separate from space.
That means time is the measure of phenomenon, not physical material. In that sense, time is one of the information that
belong to phenomena.

4. etc..

To visualise time, we invented the variety of clocks, such as water clock, sand clock, sun dial, analogue clock, digital clock, and so on.
Now we live in the community time, which is fixed by community. That make us a member of a organised community.
However, what if we could have a personal time?
