I don’t know where you live, but I experienced outage in Budapest once in at least 10 years while I lived there. And only one phase was out, not all. We even lamented with my friends that we didn’t even remember when was the last time when something like that happened. I never had to reconfigure the clock on my microwave, just for daylight saving time. I know that even 30 kms from there my granddad still experiences outages monthly, but there are places where that happens very-very rarely nowadays.
