Here's a situation from Feb, 2016.
0.8 sec left in OT#1. Team inbounds ball and player hits a 3 to win.
Replay shows that the clock didn't start quickly enough and using a stopwatch the refs showed that the shot took 1.3 seconds to release and shouldn't have counted. Basket nullified. Team ends up losing in OT#2.
Just saying that the clock isn't perfect and the refs - by rule - have the authority to change close calls.
