I have some problem with saving of correct Local Time for re-emitted photons after WLS layer.
The simulation process is shown in Geometry.gif PMT is position is shown on PMT.gif. PMT volume thickness - 3 mm
I have used the common way to obtain Local time: aStep->GetTrack()->GetLocalTime()
I adding some data txt file with saved time. There you can see that some photons have extremely small Local time (1e-5 ns), but Z coordinate of the particle vertex is the same.
PMT bottom border is at -127 mm, ZVertex of re-emitted photons are -65 mm.
I found that such unusual time appears when the photon was not detected on the border of PMT but few μm  further(txt data). Delta WLS time constant - 3 ns
I also checked that without re-emitting all is correct.
I didn't find the problem place. Can you help me, please?
