Most game clocks (well, those without tenths) are the latter (so the horn sounds 1 second after it shows 0); most shot clocks are the former (so the horn sounds as soon as it shows 0).

Next time you get a chance, try this. Set both clocks (say, 8:00 and 30). Start and stop almost immediately. Note that one has likley changed and one hasn't.

And it sounds as though Vandy's clock may be the older style where 0 really means 0 to 0.99999999.
