Talk about super-easy set-up! Simply install an AA (1.5V) battery as directed and set the hands of this clock to the correct time. The clock takes it from there. An integral microchip that is pre-programmed with a calendar tells the clock the exact days and times on which to change to Daylight Saving Time in the spring and back to standard time in the fall. No signals or antennas are required!

If you stay up late to see the clock perform the DST switching, here's what happens:

• In the spring, the hands of the clock fast-forward an hour to DST in about 8 minutes.

• In the fall, the hands of the clock move very slowly for about 1-1/4 hours until the correct standard time is shown.

Since this clock automatically adjusts for DST, you'll need to manually reset it twice a year if you live in an area that doesn't recognize DST (such as Indiana and Arizona). But for folks in most North American locations, this clock will eliminate two easily forgotten time-setting chores per year--while looking good on the wall as it does so.

For powering, we recommend an alkaline AA battery (alkaline cells are far less prone to leakage than the carbon-zinc type, and their leakage is far less corrosive). Be sure to replace the battery once a year.
