Actually, Yoix just appears to be aping Java's amusingly named <wink>
SimpleTimeZone class:

<http://java.sun.com/products/jdk/1.2/docs/api/java/util/SimpleTimeZone.html>

Yoix added just a few gimmicks, and exposed an internal implementation
detail of the Java class (endmode).  The POSIX defn of the TZ envar is
almost as complicated now!
