This thread made my head hurt, holy crap. What the hell is "foreflight time"??? Talk about over-analyzing. Time is time, there are no variations of it. If the plane is running and you are responsible for it (or SIC in an operation that requires it), that amount of time whether you look at the hobbs or your watch, is the time you log. I don't mean to sound rude or anything, but lets not be silly.
