-----update ----

just tried running the same code compiled against geant4.9.3.p01 while registering G4Cerenkov as:

     if(fCerenkovProcess->IsApplicable(*particle))
	{
	   pManager->AddContinuousProcess(fCerenkovProcess);
	}

and I see a similar error:

  G4ParticleChange::CheckIt    : the global time goes back  !!
    Difference:  0.0043225096[ns] 
    G4ParticleChange::CheckIt    : the proper time goes back  !!
