Establishing a time reference

Establishing a time reference

Hello Prophesee Team,

Is it possible to establish a time reference with the API (ideally Python)? For example, if one were to exploit the do_time_shifting functionality, could a timestamp simply be taken as the EventsIterator is called? Or is this too slow to be accurate? 
Also, I see that RAW recordings have a reference date/time in the header - is that the start of the recording, and if so, is there a way of increasing the precision of that in order to utilise it as a reference time?
I am trying to work out if using the Trigger In for this task is the only way, or whether there is a more simple route programmatically.

Thanks for your help!
