If a quantity is vector mathematically, then it must be a vector in Phsics also.
If a quantiy is scalar mathematically then it is a scalar in Phisics also.
Every one knows that time is a scalar. With out assigning a direction if a quantity can be understood, then it is a scalar.
If a quantity is a vector we can always resolve it into different componets in different directions. Atleast we can resolve it into two components one in a particular direction and the other in the perpendicular direciton.
If time can be resolved in two perpendicular directions, then time is also a vector; otherwise it is not a vector mathematically and in Phsics.
Since it cannot be done like that, time is a scalar.

I vote for a scalar. A vector needs both magnitude and direction. Time has magnitude but is has no direction. You can ask a person how much time would that take? However asking someone which direction does it point to is akward. I don't think foward counts. Now compare this to a car. In which direction is the car going or heading. Lets say North east. At what magnitude? 70 mph. Direction and magnitude.

Time is a scalar. It can be positive or negative from some reference origin; that's the definition of a scalar. If time had other components, then it might be a vector.
Space-time is a *tensor* quantity, which is a fancy kind of vector.

I would like to believe that Time is a vector...
Einstein had stated that when we travel at a speed greater than or equal to the speed of light, we can move back in time..
In other words, we can move in the -ve dir. of time (practically not feasible)... Thus, time should be thought of as a vector.

I would say scaler because time does not have a direction.

yet another vector. as an occasion, in case you multiply velocity (vector: value - velocity, course - stream course, north west south east up down...) and time (scalar: value - volume of time, no course), you will get displacement (vector: value - Distance of displacement, course - process stream, north west south east up down...)

Th sperson who just answered is wrong.. Time is scalar, because a vector contains both magnitude and direction..time doesn't.. check out the site for reference..

It is neither. Time has no direction or velocity,it is nothing more than an interval.

time is scalar because it is not defined using a direction
