Falsehoods programmers believe about time zones

i love these series of explanations.

i don't love that they are focused on misconceptions by programmers as they likely are misunderstood by many other groups. (but i understand that many of them are focused on those programming...)

what i like the most is just all the non-standard non-obvious things you learn about how the world really works.

the fact that even within a city you can't guarantee a single time zone just lays it all bare: make assumptions but don't assume them to be always true.

This article explores common misconceptions about time zones, such as the range of UTC offsets, the relationship between UTC offsets and time zones, the number of countries and time zones, daylight saving time, and more. It highlights the complexities involved in accurately representing time zones and converting between them.
