The Live Objects page does not properly forward selections. The Old Object Sample is a bit peculiar in that the events are generated when the recording is dumped. So the event start time will be the start time when the events were starting to be dumped, and the end time will be when the events were finally captured.
The time of interest for the end-user is however the allocation time, and this is what is shown in the graph. However, selections made in the graph will not properly select information based on the allocation time in the rest of the UI.
