I am having the same problem.

In the UK the clocks go forward 1 hour at 1am on the last Sunday in March, and back 1 hour at 2am on the last Sunday in October. The period when the clocks are 1 hour ahead is called British Summer Time (BST). There's more daylight in the evenings and less in the mornings (sometimes called Daylight Saving Time).

Try backing up (going backwards) with your time until the day is correct, then, add 1 (day's) date to your date (to bring it back to being correct after going backwards).

Last Sunday in March

i think you might have to change the time

The clock program for Daylight savings Time is programmed for the old "third Sunday in October" changeover. The new changeover is the first Sunday in November. The program probably cannot be updated. If there is no button or setting to disable automatic change to Daylight Savings Time you can set the time manually and then change it manually to Daylight Savings on November 1 for the time to be correct.

Sorry it took so long to give you a answer to your problem. I hope this information help you with your problem. Thank you for using FixYa and have a nice day! Dear Emerson SmartSet® Clock/Clock Radio Owner: Your Emerson SmartSet® Clock or Clock Radio includes Emerson?s patentedAuto Time Setting System that automatically sets the clock to the correct year, month, date, day and time, the first time that you plug it in, and after every power interruption. It also includes a built-in long life lithium battery that can maintain the time and alarm settings for up to 5 years, or even longer. As an added benefit we have programmed the internal SmartSet® computer to automatically adjust for Standard/ Daylight Saving Time changes through the year 2097. TheDaylight Saving Time information programmed into all SmartSet® models was based on the United States Uniform TimeAct of 1966, which formalized theDaylight Saving Time period that we observe today. CurrentlyDaylight Saving Time begins on the first Sunday in April and ends on the last Sunday in October. The new Energy Bill that was signed into law by President Bush in August 2005 includes a provision to extend Daylight Saving Time. Beginning in 2007 Daylight Saving Time will begin on the second Sunday in March and end on the first Sunday in November. Of course this is a situation that is beyond the control of Emerson, or any other company that produces devices with an automaticDaylight Saving Time adjustment feature. For example most computers, PDA?s, and many other devices also have automatic DST adjustments. Manufacturers of these devices must now begin to make adjustments to the automatic DST software to agree with the new DST timing for 2007. Beginning in 2007 the current automatic DST default settings in this device would no longer be correct. It would then be necessary for you to manually adjust the TIME ZONE setting 4 times each year as follows: 1.) On the second Sunday in March you would have to set your clock to the next lower number time zone. For example if you lived in the Eastern Time zone (Zone 02) you would then change your clock to Zone 1 to move it ahead by one hour. 2.) On the first Sunday in April, this clock will automatically advance by one hour. You must then set the clock back to your correct time zone. For example if you lived in the Eastern Time zone you would set your clock back to Zone 02. 3.) On the last Sunday in October you would again set your clock to the next lower numbered time zone. 4.) On the first Sunday in November you would again set your clock back to your correct time zone. Instructions for changing the Time Zone setting are found in the Owner?s Manual. We apologize for any inconvenience this may cause due to circumstances that are beyond our control.

I think it will be easier for you to read their directions than for me to try to explain this.

I hate to beg, but so many people don't rate solutions. We don't get paid for this we just like trying to help. If you found this information helpful I hope you'll take a moment to rate this solution.

Petewete,
Here is the manual.

Frank081541,
You can't adjust the Daylight Savings Time. I called Timex and they confirmed this.
