I bought two of these clocks and made a big mistake in doing so. The "automatic setting" for time was fast (by 6 minutes) on both clocks. Neither could be adjusted, and to make matters worse, over the last few months the clock has sped up and is now 11 minutes fast. At least I won't miss any appointments. I long for simpler days - a a clock that is accurate and adjustable and is easy to use. This one fails miserably.
