When you are setting timing you are setting top dead center and bottom dead center. Once established based on the marks on the crank and cam you adjust top dead and BDC by degrees in ADVANCED timing or behind/retarded timing by degrees by counting links. Each link used to be 5 degrees. Check repair manual on link values! they change with each engine and maker.
