Dear Radek,

this produced some interesting results. First, let me show you the number I got from a simulation of just 10 events:

ioManager->GetEventTime(): 8.89033   myEventHeader->GetEventTime(): 8.89033
ioManager->GetEventTime(): 239.621   myEventHeader->GetEventTime(): 8.89033
ioManager->GetEventTime(): 290.828   myEventHeader->GetEventTime(): 239.621
ioManager->GetEventTime(): 300.156   myEventHeader->GetEventTime(): 290.828
ioManager->GetEventTime(): 312.479   myEventHeader->GetEventTime(): 300.156
ioManager->GetEventTime(): 382.595   myEventHeader->GetEventTime(): 312.479
ioManager->GetEventTime(): 386.654   myEventHeader->GetEventTime(): 382.595
ioManager->GetEventTime(): 428.155   myEventHeader->GetEventTime(): 386.654
ioManager->GetEventTime(): 439.536   myEventHeader->GetEventTime(): 428.155
ioManager->GetEventTime(): 445.36   myEventHeader->GetEventTime(): 439.536
ioManager->GetEventTime(): 445.36   myEventHeader->GetEventTime(): 445.36
ioManager->GetEventTime(): 445.36   myEventHeader->GetEventTime(): 445.36
ioManager->GetEventTime(): 445.36   myEventHeader->GetEventTime(): 445.36
ioManager->GetEventTime(): 445.36   myEventHeader->GetEventTime(): 445.36
ioManager->GetEventTime(): 445.36   myEventHeader->GetEventTime(): 445.36
ioManager->GetEventTime(): 445.36   myEventHeader->GetEventTime(): 445.36
ioManager->GetEventTime(): 445.36   myEventHeader->GetEventTime(): 445.36
ioManager->GetEventTime(): 445.36   myEventHeader->GetEventTime(): 445.36
ioManager->GetEventTime(): 445.36   myEventHeader->GetEventTime(): 445.36
ioManager->GetEventTime(): 445.36   myEventHeader->GetEventTime(): 445.36


After simulation, I have 10 events in the root file as defined in my macro. After digitization I have 11, which is also expected, but after reconstruction there are 20. However, looking at the output above the last 10 seem to be more or less the same. Also, it is noteworthy that the FairEventHeader lags one event behind the FairRootManager. Overall, it looks like a step in the right direction!

Cheers,
Michael
