None Time of particle decay

Hello everyone.

I am using the /gps macro commands, and using the radioactive decay manager. In my macro
file I have, for example, the following lines to generate my events:

/gps/energy 0 keV
/gps/particle ion
/gps/ion 27 56 0 0
/gps/time 0 ns

This will generate Co-56 nuclei at rest, and the RDM then handles the decay.

For any individual event, Track 1 is the ID of the track of the original Co-56 nucleus, and so
theTrack->GetGlobalTime() is always equal to 0 (because I explicitly set it so in the macro
file).

Here's my question: How do I find out at what time the Co-56 nucleus decays? I can't simply
wait for Track 2 to appear and read off the GlobalTime(), because Track 2 might not be the first
track that is processed. To be more explicit, I would like to subtract the decay time from all
other calls to GlobalTime(), so that I can start the clock when the decay occurs, and not when
the Co-56 nucleus is created in the first place. And again, this determination has to be
independent of the track ID.

Any suggestions?
