I will miss the approach, confer with ATC, and either return for the LOC only approach, an entirely different approach, or I will divert to my alternate. Of course if I were in an emergency situation, all bets are off and I might well consider a loc only approach. As for time, I call for time to start over the outer marker or FAF, not at GS intercept
