There's something jarring about daylight saving time (DST). It messes up my sense of beauty and consistency. Below you'll find a quite beautiful map of timezones around the world. You'll notice that, for the most part, countries' timezones roughly correspond to their longitudes; the colors showing timezones are in fairly straight lines from south to north.
Except, this is only true in standard time. During about half the year, the colors of most of Europe and North America shift leftward, and during the other half, some areas in South America and Oceania are shifted rightward.
Another jarring aspect is the fact that midday, when the sun is highest in the sky, doesn't occur at or even near 12 p.m. Instead, DST causes midday to occur on or around 1 p.m. Below, you'll find a graph displaying sunrise and sunset in Greenwich, which logically should be centered around noon, but during DST they are shifted one hour toward the evening.
The final jarring aspect I'd like to mention is the fact that due to DST, some times never occur, while others occur twice. If you've ever stayed up, watching your phone or computer clock switch 01:59 → 03:00 a.m., you'll recognize the weird feeling (this is when the switch in Sweden occurs). And because of DST, dates and times are rendered ambiguous, as 02:15 a.m. occurred twice on October 28th, 2018 in Sweden.
