In this study, we consider time-like regular surface in Minkawski space as y = y(u, v) and investigate Darboux vectors of the time-like curves on time-like surface as (c), (c(1)) and (c(2)) which are not intersect perpendicularly. Moreover, we give a relation between the Darboux vectors of these Darboux frames. By this relation we obtain general Liouville formula and general form Euler and O. Bonnet.
