The dynamical evolution of a spinning gauge string is investigated. We find that the formation of closed timelike curves in these models is exceedingly unlikely, because they require unrealistic values of the gauge-string parameters, probably found in the spacetime surrounding a supermassive string. The junction conditions across the boundary layer of the interior and exterior string solution are investigated. The time evolution of the string core radius, in a simplified model, is numerically obtained. It turns out that the evolution of gΦΦ cannot be made consistent with the motion of the core of the string. The behavior of the core of the cosmic string, measured in the interior time, shows that the appearance of the causality-violating regions is an expression of the helical structure of time.
