We review the generalization of tunneling time and anomalous behaviour of Faraday and Kerr rotation angles in parity and time 
systems. Similarities of two phenomena are discussed, both exhibit a phase transition-like anomalous behaviour in a certain range of model parameters. Anomalous behaviour of tunneling time and Faraday/Kerr angles in 
systems is caused by the motion of poles of scattering amplitudes in the energy/frequency complex plane.
