This is a nitpick, but the first sentence bothers me. Theoretically, the world shouldn't be divided into time zones at all, but rather one continuous timeline, where local noon is always when the sun is at its highest point.
I don't actually object to timezones (I'm not nuts!), and they do discuss local mean time later on -- but for a piece trying to explain them, it seems odd that it starts by arbitrarily positing 24 equal 1-hour timezones as the most "natural" time.
