This is clearly non-portable. TZ isn't set here, and I would never
rely on any environment variable, esp. if your program runs as a
system user (news in this case).

mktime -- at least on my glibc-2.1.2 Linux system -- sets the
external variable tzname correctly (to EST in my case).

What we need to have answered are the following questions:

- Does time( NULL ) return seconds since the epoch in local time?
  (Yes according to MA)
- Is tm_gmtoff "time(NULL, UTC) - time(NULL, local time)" or vice
  versa?
- Same question for timezone.
- Are the answers of the two previous questions the same east
  and west of GMT?
