A dimension (in Geometry) is the direction in which a body can move in space or an event happens in time. One hour into the future is real, but without known events. One hour to the past is real, but events do not exist anymore. Time exists in the future and in the past, but events only exist in the present. We know that tomorrow will occur inexorably (dimension), but we do not know what events will occur. If we travel to the past or to the future, we would cease to exist. Because of this it is not possible to travel in time. In clocks we see a periodic phenomenon that occurs in the present.
Isaac Newton said: "Time is like an invisible river in which everything happens." The invisible river is the dimension of time.
In conclusion, time is composed for a dimension (real) and events occur in it.
