i do not know if you need the time exactly as reported by that function
or if you just need to be able to order the events. if it is the latter,
why not just use a counter that is incremented each time the event
occurs? if all you need to know is if one keypress occurred before the
other, why not use a circular buffer to store the keypressess and let
the other functions retrieve them on a FIFO basis?
