Who does not know the time? Everyone knows it's time for what. But only a few who know the actual function of time. Basically when aiming to tell us the year, month, day, hour, minute, second and so on. It was simple but have you ever thought why humans eager to create a time machine?
Humans want to create a time machine to change the past so that the
future is obtained as expected by a "traveler" (designation for service
users time machine).
Back on the function of time, time actually has the following functions:
1. Time as a basis to show our state in the position we are experiencing
2. Time showed extraordinary events that sometimes we have never experienced before3. Time is used to mark a specific occasion4. Time is always positive (moving forward) and never the same, for it is a lot of remorse arise that occurred in the past5. Time is an opportunity for us to change.
