Although the trope is hilarious I think most people just don't bother since it doesn't matter to them. I never had a problem setting the time on my VCR and using it to automatically record shows while I was at work.
Different neighbors, being on different circuits, being on a line that's more likely to have storm damages, can make a lot of difference in quality of power delivery.
I've lived in places where the power practically never went out, never experienced undervolt situations, etc. I've then lived less than a mile away from the same place and experienced seemingly monthly issues of all the clocks being reset at random times when I come home. Living closer to things like hospitals, fire stations, emergency operations centers, etc. seem to give the best indication of power reliability, at least from my personal experiences.
