For United States residents only – In case you already haven’t done so or your clocks have not updated themselves, be sure to move your clocks 1 hour ahead. Most automated devices including cell phones, computers, and atomic clocks should have made the change at 2:00 a.m. local time. The clocks will fall back an hour on November 2nd. My Vista Laptop, XP Laptop, and my Cell Phone changed automatically at 2:00 a.m., however for some reason I had reset my Oregon Scientific atomic clock.
