Tunneling doesn't mean jumping. The probability wave of the particle does exist inside the barrier, see e.g. https://commons.wikimedia.org/wiki/File:TunnelEffektKling1.p... So yes, it "tunnels" through the timer field also, but the probability of interacting with the timer field is not zero.

I would be interested if the Lamor clock also shows a shift in the reflected particles. Because that would mean, also the reflected particles spend some time inside the barrier.

Of course, but it is less than one. Hence the measurement underestimates the proper time interval.
