A dimension is different than a coordinate. A dimension of physical system is a degree of freedom the system can move about back and forth. Because you can not move back and forth in time, then time is NOT a degree of freedom.

We do not move in time (try to slow down or accelerate, or to move back).

If you think we DO move in time, then what is our speed?
