This thing is essentially a hotel room alarm clock that is factory pre-programmed with the time and date in the US Eastern time zone. The 2032 battery holds the programming so that when it is plugged into a power source, it comes alive with the date and time, which in my case was 2 minutes fast. I'm assuming it also has the dates of future DST changeovers programmed into it, but it does not pull down time signals from the atomic clock or any other source. The second paragraph of the Instructions, headed "How does the autoset technology works [sic]? says as much for anyone who cares to take the time to read it. **Q: Is this product any good?** A: Yes, very good! I got it for my daughter. It automatically keeps up with the time, just like our cell phones. The alarm works great. I recommend it. **Q: how long is the power cord?** A: Power cord is 5 feet long. **Q: Can it turn off for 10 minutes and go back on. And still have the battery, will it charge?** A: All I can say is that we had a short few minute power out and with other old digital clocks, I had to reset the clock. This clock wasn’t affected and I believe it is because the extra battery is the instant backup. Hope that helps. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by B***. on 15 February 2026* This clock is the easiest to set up! ### ⭐⭐⭐⭐⭐ Review *by M***S on 23 January 2026* It works properly. ### ⭐⭐⭐⭐⭐ Review *by C***R on 16 January 2026* works great and its very nice ## Frequently Bought Together - DreamSky Alarm Clocks for Bedrooms, Auto Set Digital Desk Clock for Bedside Nightstand, Electric Clock with Dimmable Brightness Dimmer, Auto DST, USB Port, Date, Temperature, Snooze - Sharp Digital Alarm with AccuSet - Automatic Smart Clock, Never Needs Setting - Great for Seniors, Kids, and Everyone who Doesn't Want to Set a Clock!
