Hi,

I am simulating a gamma counting experiment in which the timing of events is of interest: i.e. when does one event occur in relation to a time=0 defined by the generation of the first event. I attempted to output time in my implemented UserTrackingAction->PostUserTrackingAction method by calling fpTrack->GetProperTime(). Although similar calls for the local and global times come out fine (for length of track and event times, respectively) -- Proper time (which I assumed is simulation-system time?) is a constant 0 even after millions of events.

I have referred to the online documentation, but I cannot seem to find much on this topic. Any insight into how GEANT keeps global timing would be appreciated -- for example, I am unaware of setting any kind of rate for the generation of primaries, so how would geant track this variable? does it? Do I have to impose such a global time distribution in post-simulation analysis? If such inter-event time-keeping is possible, what methods are availabe to access it or adjust it?

Regards, and thanks! mark
