AMIGA detectors are highly segmented devices and, as such, posses the capability of measuring the arrival times of individual muons at a depth of 2.3 m. Nevertheless, the lack of information of the exact position of a crossing particle along the scintillator strips (of 2m or 4m length depending on the module area) results in an unavoidable uncertainty in the reconstruction of its arrival time. In this work, we analyse the delay in the signal for triggering-particle positions spanning from the closest to the farthest ends of the scintillators using well controlled laboratory measurements. The resolution of the reconstructed times observed is 12 ns.
