every play it resets. It seems like a long time on TV, because TV time is warped a bit, but IRL or at the game it goes by very quickly. There is a lot to do. Not only what i metioned above, but players go in motion to distract or to set something up, a nd QB's "read" the defenses to see if they need to change the given play (audible to a run or to a short pass , etc.)
That is why you cannot have stupid people playing QB

I don't like seeing broken bones come rupturing through flesh. eeep.

oh! ok... that makes sense now. 40 seconds. so you can use up to 39 seconds if you're ahead on the score, or hurry the fuck up & take the ball out of bounds if you're behind. i see. it... begins to make sense, ha ha ha.
