    "abstract": "In (quant-ph/0701141) Rajeev studied quantization of the damped simple\nharmonic oscillator and introduced a complex-valued Hamiltonian (which is\nnormal). In this note we point out that the quantization is interpreted as a\nquantum mechanics with {\\bf complex time}. We also present a problem on\nquantization of classical control systems.",
