When I look at an analog clock, I'm not looking for the actual time. I look at where the minute hand is in relation to where I want or need it to be. If I have to leave my house at 12:40 or "twenty minutes before one", all I need to know is how close the minute hand is to the "8". Of course, I first verify that twelve o'clock has passed and it's not actually 11:40 or, worse yet, twenty minutes before two!!
