Time Zones ?#!@!

Yesterday, I asked the world about time zones, OS X, and the idiosyncrasies and complexities of conversion.

I asked Mark Anderson whether he could narrow down the problem. The redoubtable Mark Anderson promptly pointed out that “12/31/1883” is off by a day, but 1/1/1884 isn’t.

What on earth is special about 1884?

Four standard time zones for the continental United States were introduced on November 18, 1883.

So, our handling of the shuffle between the local time zone and universal time apparently needs to take into account that time zones don’t exist before 1883? Does OS X really know about the invention of the railroad?
