Solar time vs Standard Time

"Noon" should be when the sun is directly overhead, right?
Well, not really.  As Stefano Maggiolo points out, its pretty much almost never the case that the two align
It turns out, there are many places where the sun rises and sets late in the day, like in Spain, but not a lot where it is very early (highlighted in red and green in the map, respectively). Most of Russia is heavily red, but mostly in zones with very scarce population; the exception is St. Petersburg, with a discrepancy of two hours, but the effect on time is mitigated by the high latitude. The most extreme example of Spain-like time is western China: the difference reaches three hours against solar time.
