Abstract
In the present work we propose a generalization of tunneling time in parity and time ()-symmetric systems. The properties of tunneling time in -symmetric systems are studied with a simple contact interactions periodic finite size diatomic -symmetric model. The physical meaning of negative tunneling time in -symmetric systems and its relation to spectral singularities is discussed.
