A maintained variant of Mail/mailx uses a different approach which hopefully works (with/out .tm_gmtoff) correctly.
Its "ifdef mx_HAVE_TM_GMTOFF" code looks OK, but when mx_HAVE_TM_GMTOFF is not defined that code is obviously wrong near the start or end of the year. For a better approach, see zdump.c's gmtoff function.
