Personally I log airbourne time + 5mins either side which certainly used to be the norm but its probably all changed by now!
I seem to remember reading somewhere that as soon as an aircraft moves under its own power its loggable which would fit in with the above. I dont think I'd log 20mins of taxing around the apron however unless its for training in which case I suppose its valid experience, especially in a tailwheel which can need close attention at all times the engine is running!
