Well, time is not a vector.

Time is, what the clock is showing (Einstein). That's all there is to time. (Essentially it's something humans invented for their convenience. Some physics even go so far, as to abandon this concept for their theories and it seems to work.)

But, at the end, it depends on how the author is seeing the concept of time.
