TO but shot clock shows 24

[luvhoops]

In backcourt, Trail is officiating heavily guarded/pressured ball handler A1. Team A coach requests a timeout. Trail official acknowledges/grants timeout called and stops the clock. Officials look at shot clock which reads 24. Center official claims that the shot clock had started 2 seconds early, although he did not rectify it when it actually happened. No official had any direct knowledge (count in head, etc) of actual elapsed time. No monitor or other help from anywhere/anyone.

Would you grant the timeout and leave the shot clock at 24?

Would you grant the timeout and put the shot clock at 26?

Would you call the 10-second violation, give the ball to Team B, but still grant the timeout?

Would you call the 10-second violation, give the ball to Team B, and not grant the timeout?

Would you do something else?

With answers, please provide a brief explanation.
