I figured this out by looking at timeanddate.com and comparing their data
to my output.  I've got that time zone fixed, along with Europe/Vienna.
Now if I can fix a few others, I think I'll actually have the whole damn
thing fixed.

The Olson database is a huge PITA to deal with.  No docs on what things in
it _mean_, nor any set of output to compare it to.  And the only free
software code I can find to compare mine to is the zic program that comes
in the tzcode distro, which is a maze of nasty C code.  Ick.
