Oddity three years ago . . . according to my rusty memory:
Scoreboard minutes and seconds worked great but the tenths of seconds, we were told by the AD prior to the game, didn't work. Wouldn't you know it. Whistle near end of a period stopped the clock at 0:0 but the horn didn't go off. Home coach, desiring to set up a play during a timeout, asked if we could go to the scoreboard operator's console at the table to identify if there was .3 seconds or fewer left on the clock. (At least he knew the rule!) As I recall the console display showed .2, so we knew the next play had to be a tip.
Looked it up later where 5-2-5 says "...three-tenths (.3) of a second or less remains on the clock...". Doesn't say which display, so as long as both coaches and all the officials knew the situation, we justified our actions in that case.
One in a million circumstance, I guess.
