Penalty following change of possession

B24 intercepts A's pass and during the return the covering official blows an inadvertent whistle. B24 was at A's 9 yard line when the whistle sounded. The box is set and just prior to the ready for play, B's coach requests and is granted a time out. B's coach is irate, feeling that a sure touchdown has just been taken away and he sounds off at the official who had the inadvertent whistle. He is subsequently flagged for an unsportsmanlike conduct. After marking the penalty, are the chains reset or is it 1st and G at the 24 yard line?

According to what we have been told, it should be 1 and 10 from the 24, but I think this gives the team penalized an advantage. What does everyone else think?

I've actually heard some discussion that leaves it debateable. No consistency exists because there is a possibility of a delay between when the sticks are set and the whistle to signal RFP. My belief is that the RFP whistle is the point where the penalty application changes.

Therefore, I believe that 1D/10 @ 24 is the proper call.
