Time Zones vs. Mean Solar Time
Halibut writes:
March and April are the time of year where a decent fraction of the world shifts their clocks forward (or back, in the Southern Hemisphere) for Daylight Saving Time (DST). Every year, it seems to result in debate about whether to abolish DST, and, if so, whether to stick with standard time or daylight time.
Soylent News, being a science/fact-oriented site, would likely be interested in a comparison of time zones with Mean Solar Time (MST). There is a map showing the difference between the two in the Wikipedia article on time zones. The person who created that map has some short-yet-interesting articles on creating that map and later discussion about it. The articles are old (timeless?), but largely still relevant, as the time zones, and the existence of DST, are largely unchanged since the articles were written.
Interesting how standard time, over most of the landmass of the world, is largely ahead of MST, in some places (e.g. western China) by a lot. DST, where observed, makes that difference worse.
