    "abstract": "For the Toda lattice and the Holt system we consider properties of canonical\ntransformations of the extended phase space, which preserve integrability. The\nseparated variables are invariant under change of the time. On the other hand,\nmapping of the time induces transformations of the action-angles variables and\na shift of the generating function of the B\\\"{a}cklund transformation.",
