I have a radio Shack Atomic Wall Clock 63-1438 and the time didn't change on Oct 31, 2009. Should it automatically change of do I have to reset the clock?

If the atomic radio controlled clock is off by one or more hours, it probably has to do with the time zone setting. ... Other atomic wall clocks may allow the selection of any time zone, even time zones that are outside the WWVB coverage area. When purchasing a clock, make sure that it can display the correct time zone. https://www.weathershack.com/static/ed-atomic-clock-synch.html

Hit the set button until the number 24 shows up instead of the time. Hit the "+" button once, and it will switch from 24-hour to 12-hour display. Hit the set button to cycle through the rest of the settings.

The easiest way to reset it would be to change it to Eastern time - that will give you the correct Central DST.

It should automatically reset to the correct time. Try taking the model number and Google for an answer. Hope this helps.

Press and hold the set key until time zone appears, then + or - to your zone.

how do I change my atomic clock to eastern time zone. Or when I set my time does it automatically set to the correct time zone.

My similar unit from Radio Shack took over four hours to communicate with the atomic clock.

press set button repeatedly -you get timezone mode and change your wished time zone and select your zone then press set button to normal mode and adjust the current time.
thanking you.

so long as the US atomic clock adjusts their daylight saving times then you should be fine check this link for some more details (about the scr 110 but seems to be basically the same) http://www.amazon.com/H-H-Scott-SCR110-Atomic-Clock/dp/B00004TZDN/ref=sr_1_2/104-1966292-9407907?ie=UTF8&s=electronics&qid=1173502881&sr=1-2 hope this helps :)
