Time display is always accurate because it's regulated by a radio signal continuously received from the government's "atomic clock" in Colorado.
And you'll know exactly what to wear each day, because the outdoor temperature is also displayed, thanks to the wireless remote temperature sensor included; 80' range. Unique LCD "Weather Man" gives you an idea how much you need to wear to stay warm (based on barometric pressure)!
LCD digital display shows hours, minutes and seconds (12- or 24-hour format), day and date, plus inside and outside temperature, and indoor humidity. Time alarm with snooze. Time-zone setting; DST on/off option. Calculates sunrise/set based on your location. Night-view backlight. Signal-reception indicator. Hangs on wall, or use easel stand. Clock is 4-1/4"x6"x1-3/16" thick and is powered by three AA batteries (sold separately). Wireless outdoor sensor requires two AA batteries (sold separately).
