How to record time of arrival?

Hello! I am relatively new to Geant4. I have simulated a scintillation detector and want to record the arrival times of optical photons arriving at the photocathode of a photomultiplier tube. So I want to end up with a plot of amplitude against time. Can anyone give me some guidance on how I would do this? I have assigned the photodetector as a sensitive detector to record ‘hits’ - Do I use GlobalTime() to get time of arrival? And how can I get a histogram of amplitude against time for this? T…
