Linear and nonlinear Hamiltonian systems are studied on time scales. We unify symplectic flow properties of discrete and continuous Hamiltonian systems. A chain rule which unifies discrete and continuous settings is presented for our so-called alpha derivatives on generalized time scale s. This chain rule allows transformation of linear Hamiltonian systems on time scal es under simultaneous change of independent and dependent variables, thus extending the change of dependent variables recently obtained by Dosly and Hilscher. We also give the Legendre transformation for nonlinear Euler-Lagrange equations on time scales to Hamiltonian systems on time scales.
