Many electronic devices in the US have functionality in them to automatically adjust the clock when there are changes in daylight savings time. Unfortunately for older devices, they didn't account for the fact that congress moved the time so that daylight savings time would be extended. Last week was the "normal" weekend for the end of daylight savings time. So if you have a device that adjusts for daylight savings time, it's clock is now probably wrong since daylight savings time doesn't actually end until next weekend now. You'll want to adjust that clock. And if possible you'll probably want to turn off the feature that automatically adjusts for daylight savings time.
