This is a problem with either the a/c power or the Clock/Radio's internal timing crystal circuitry. The radio depends on the 60 cycle power source as the timing device. If this power is irregular or uneven in its delivery it can cause the timing circuits to lose or gain time. The Clock/Radio has a frequency tuned crystal that operates like the second hand on a clock. When the calibration for whatever reason is lost the crystal will not be able to perform the timing function correctly. The reason this does not happen in all Clock/Radios is that they usually have correction circuits. These circuits keep the crystal from drifting out of calibration during operation. Because of the low production cost of these Clock/Radios, the quality control is almost non existent. The components are variable and sometimes they do not stay within specifications. This problem is usually handled by quality control departments in the manufacturers facilities. They usually test a certain amount of the production run to make sure it meets specification. In higher priced electronics these test are on going during the production run. In lower cost electronics these tests for quality control are usually done before the production run. This is to choose the best and most reliable components for the price level of the product in production. What this means to you, is that the quality of the components and quality control of the production runs are based on cost efficiency to the manufacturer. This is the reason for these type of efficiency variables in the products. The customer support telephone number for Emerson is 1-800-898-9020 between the hours of 9am-5pm CT. Give them the make and model number of the Clock/Radio and ask them for assistance with your problem. I hope this information helps you under the problem and reason these problems can occur in the products.

Place your Seth Thomas atomic clock face-down on a table or desk and locate a series of buttons labeled "PST," "MST," "CST" and "EST" on the back of the clock. Press the appropriate button to set the time zone.
Turn your attention to the small lithium battery-powered digital clock display on the back of your clock. With the correct time zone set, the digital display should accurately reflect the current local time.
Locate the AA battery compartment on the back of your clock. Put two new AA batteries into your clock's battery compartment.
Set the "Mode" switch on the back of your Seth Thomas atomic clock to "Run." Wait for it to adjust to the correct time. The automatic time-adjustment process can take up to 45 minutes, but is usually completed much sooner.

joedgrier's clock is a SmartSet
Correction: Megwall's clock is a SmartSet!!
Mine is 5 minutes fast
When I bought my Emerson clock radio home yesterday and plugged it in, its clock was 3 minutes off from my PC's clock, which is set from the atomic clock. I have no idea why it would be different. My workaround is to just set the Emerson's clock to match the atomic clock. This new, corrected time is what gets restored if the Emerson ever suffers from a power failure, and I'm happy with that.
Short of some kind of firmware upgrade, I don't see how there would be any solution to this.
