Waking/alerting people with a random offset time added to a pre-programmed wake-up/alert time, the improved method and apparatus disclosed in the present invention maximizes time confusion and uncertainty to provide an extra urgency to get up and/or get ready. In an embodiment, an alarm clock chooses a random time offset of D minutes without the user's knowledge. The alarm sounds D minutes before the preset wake-up time while displaying the current time plus D minutes. Thus, even though a user realizes that the alarm has sounded earlier than the preset time, he does not know exactly how many minutes earlier. Alternatively, the alarm could sound D minutes after the preset wake-up time. Again, the user does not know how much offset has been inserted by the clock. This uncertainty forces the user to assume the worst-case and get up quickly.
