Obviously all are textbook speakers who didn't do experiments much in their study life. When you measure temperature of a hot object using a say mercury thermometer, you must wait the reading up to a constant value in which they are under thermal equilibrium. Otherwise that measured reading is not valid according to this instrumental instruction (the zero law).
