Our Smartset technology automatically sets your clock to the correct Year, Moth, Day and Time as soon as you plug it in. Just select your time zone and the built-in computer does everything else for you immediately. If the power is interrupted for any reason, your clock will automatically rest itself once power is restored. Additionally, the SmartSet computer accounts for Daylight Savings Time and will adjust itself automatically. No longer spend time setting and re-setting your clock, Emerson's SmartSet technology has you covered.
