We've had this discussion many times before, but I log the time from the engines are turning to the times the engines are shut down/Hobbs. That's all PIC time in my book. It's not like there are no qualified skills that you have to train for not involved in the startup (awkward sentence), nor would my pilot's licence be any less on the line legally if something should happen when the engines are turning but aircraft not moving, nor would I be able to conduct flight at all without them turning - they are an intrinsic part of flight and a requirement. So to me that's all loggable time. I will only refrain from logging that time if flight does not take place, or if I'm turning engines unusually long before I move under own power.
I know a lot of people disagree with this way of logging, but I think it's the correct way to log.
