i just had an idea. you could set a timer event to trigger every 1 
millisecond. then you could use those events to set a rough timestamp 
for events in-between the timer events.

unfortunately timer events are usually pretty low resolution on most 
systems. i have a feeling the lowest you can go is probably 10ms. still, 
that's enough for a rough ballpark on timestamps. to set up the timer 
events is a simple call

    pygame.time.set_timer(pygame.USEREVENT, 10)

then events with the type 'USEREVENT' will magically start appearing 
every 10ms. you may actually want to raise the time interval if you 
don't need such accuracy, since this will still be creating 100 events 
per second. something like 500 or 1000 might be better?
