I was afraid of something like that.

On SVr4 systems, timezone is declared:

        extern time_t timezone;

and is the offset from UTC, set automatically when localtime() and friends
are called.  BSD instead uses the tm_gmtoff member of struct tm, which
isn't present on SVr4 systems.  We already have an autoconf test for
tm_gmtoff; it needs to be expanded to test for either it or for a usable
timezone and then the time-related code needs to take the results into
account when finding the time zone.

Standard sort of inter-Unix gratuitous incompatibility.
