Well, obviously there's ambiguity as to which sort of direction on the manifold we can identify with time. There is no definitive direction that is associated with time, and different observers will see time as being different directions on the manifold. But then, this is the same with all other directions as well, so time isn't exactly special in regard to this ambiguity.
so may i say that time is a direction but the answer of WHICH DIRECTION changes with observer?????
or may be that time exists within the three dimensions of space occupying some part of all three dimensions?????
