  We begin the Article with confusing citations in published papers on the
question recently: how much time does a wave packet spend in a tunnelling
barrier? ..a particle tunnelling through a barrier appears to do so in zero
time 1. .. The pulse transit through the barrier itself seems to be
instantaneous 2. ..tunnelling is unlike to be an instantaneous process 3.
..ionization time is close to zero 4. ..all waves have a zero tunneling time
[5]. ..Our results are inconsistent with claims that tunnelling takes zero time
