g, we're getting hung up on a misunderstanding here. I don't think we disagree about anything. The check is 'get rid of your alarm clock, see if you can still wake up at the right time'. Nothing else needs doing. If you have a job pressing the world-not-explode button at precisely 9am every morning then you might need to do something ever-so-slightly more complicated to allow for that. But not much more complicated. You know my number, give me a ring if I'm not making sense.
