I think what they meant was an outage so short that it will reset the clock on the microwave/stove/bedside alarm but that you don't notice it otherwise. In the northeast, these happen frequently overnight, usually due to minor weather events or grid maintenance.

Most of my clocks are internet connected and battery backed, so the only ones left in my house that are affected are on kitchen appliances.

I think they mean the latter. When I lived in rural Wisconsin we'd get those at least once a month in the summer, usually from thunderstorms. The lights would go out for a second, and the clocks would start flashing 12:00. Haven't seen it happen since moving into town though.
