Abstract
Spin precession and phase delay are two methods for defining "clocks" which can measure tunneling times. That these two methods in some cases do not predict the same tunneling time has caused much controversy. In this paper, we re-analyze the spin precession method of Büttiker and find that if the magnetic field is applied throughout the space, the spin precession and phase delay times agree with each other.
