When we watch a clock, how can we read it?
See this picture of a clock.
Can you know what time it is?
Even though you are a prophet, you can't say it to me. Because, the clock is completely symmetric. To read the clock, its symmetry must be broken. Unless broken, there is no way to read it.
Again, see the picture following,
You may know what time it is.
This is because the time is naturally asymmetric for past and future. The future will come now and become the past. Furthermore, the past cannot return to now. It is impossible to make the time-machine.
Can we move in time freely if the symmetry of time will be recovered?
