    "abstract": "The time operator canonically conjugated to the Hamiltonian of $N$\ninteracting particles on the line is constructed using SU(1,1) as a dynamical\nsymmetry. This hidden conformal symmetry enables us to make a group theoretic\nanalysis of the time operator in terms of SU(1,1) generators. At distances very\nfar from the interacting region the time operator is represented as a\ngeneralization of the quantum \"time-of-arrival\" operator.",
