The proposed change is really a kludge, not a fix! How about innocent
Mush users outside the EST/EDT timezone? You don't really want them
to edit the source again and again ...

Basically, the code in dates.c::rfc_date needs to be upgraded for the
case of a BSD4.3 system which uses the /etc/zoneinfo system for
establishing timezones. This includes (as far as Gould is concerned)
UTX/32 2.1 and later (PowerNode), and UTX/32 3.0 and later(NPL).

The following context diff shows how this can be done. Presumably
Dan Heller can turn this into a generic fix for BSD4.3 ++ systems
sometime ...

      tz = timezone(myzone.tz_minuteswest, (T->tm_isdst && myzone.tz_dsttime));

      char *tz = "";
  #endif /* BSD */
