According to my book, and wiki http://en.wikipedia.org/wiki/Hamiltonian_mechanics#As_a_reformulation_of_Lagrangian_mechanics,
##\frac{\partial{H}}{\partial{t}} = - \frac{\partial{L}}{\partial{t}}##, where ##L## is the Lagrangian.
But how can this be? This assumes the generalized coordinates are independent of t, but that's not the case for dynamic systems.
