With reference to this code:

Shoot.
Looks like FreeBSD provides a timezone() function which they admit[1] is
not POSIX compliant[2]. And their time.h[3] doesn't seem to have any
kind of variable that gives the same functionality...
I guess what's needed is to:
- check for the variable at configure time
- if we don't have it, call localtime() to get a struct tm, and pull the
timezone offset out of there
Maybe the first step can just be skipped for simplicity, though. I'll
try to get to that tonight unless someone beats me to it.
