We study the time \(T\)-map \(U\) which maps initial data \(\left(u_{0}, u_{1}\right)\) to the solution and its derivative \(\left(u(T), u_{d}(T)\right)\) of the homogeneous wave equation in a domain with time \(T\)-periodic boundary. The spectrum of \(U\) and the type of the spectrum are completely
