The cross product yield vector represent the area between 2 vectors and volume in 3 vectors if we Cross the unit time vector and space vector what will Yield ??

Hello every one i have question what is the unit vector of time component like c^2 t^2 -x^2-y^2-z^2 = 0 OR if we need to calculate the d'alembert cross some 4 vector have 3 space component x y z and unit vector i j k and ct component what is the unit vector in Ct direction ?
