    "abstract": "We show that it is impossible to determine the time a tunneling particle\nspends under the barrier. However, it is possible to determine the asymptotic\ntime, i.e., the time the particle spends in a large area including the barrier.\nWe propose a model of time measurements. The model provides a procedure for\ncalculation of the asymptotic tunneling and reflection times. The model also\ndemonstrates the impossibility of determination of the time the tunneling\nparticle spends under the barrier. Examples for delta-form and rectangular\nbarrier illustrate the obtained results.",
