I agree that time is literally the fourth dimension, although I don't
know that we CAN travel along it in only one direction.  We HAVEN'T,
but does that mean we CAN'T?  Perhaps people in our future have the
necessary technology (and the wisdom not use it).  I think any consideration
of trying to improve the past would be offset by the risk of accidentally
making it worse.
