0 seconds on the clock, Stop the game?

[Jimgolf]

We had this happen during two games this weekend. We have an old scoreboard, with a new controller. The controller shows tenths of seconds, but the scoreboard does not. The controller shows 0.9, 0.8, 0.7 seconds, but the shot clock shows 00:00, so the officials blow the whistle, saying end of quarter. I explain the situation to them, and we proceed with no further issues the rest of the day, with me warning subsequent officials.

Anyone run into this before? Any suggestions? (Like maybe the scoreboard controller or the scoreboard could be altered to match each other?)
