Problem with atomic clock updating

Popular radio-controlled timekeepers, which range from wristwatches to wall clocks, are not really atomic clocks -- though that's often in their name -- but they do set themselves by listening to low-frequency AM time broadcasts from the NIST radio station WWVB in Fort Collins, Colo.

Those broadcasts are synchronized to the NIST atomic clock ensemble in nearby Boulder, Colo.

NIST is changing the way it broadcasts time signals that synchronize radio-controlled "atomic" clocks and watches to official US time in ways that will enable new radio-controlled timepieces to be significantly more robust and reliable.All parts of the display are large enough to read across the room.It is also readable from many angles which is a huge bonus as that meant we could pick a centralized mounting location. I have a Acurite wireless unit for my greenhouse and a pro level La Crosse one attached to my PC.Both the clock and outside sensor use 2 AA batteries.This was of importance to me as we use rechargeable batteries and look for equipment which doesn't use an odd battery.However, sometimes the radio-controlled clocks have difficulty accurately picking up the WWVB time signal because of the clock's location, local radio interference, effects of buildings, and other problems.
