The glibc documentation says: "The `tm_gmtoff' field is derived from BSD
and is a GNU library extension; it is not visible in a strict ISO C
environment." So it should be OK for Linux and *BSD, but may still need
an autoconf feature test for other platforms.
Also, the meaning of tm_gmtoff is not the same as the global timezone
variable:
-- Variable: long int timezone
[...]
Unlike the `tm_gmtoff' member of the broken-down time structure,
this value is not adjusted for daylight saving, and its sign is
reversed. In GNU programs it is better to use `tm_gmtoff',
since it contains the correct offset even when it is not the
latest one.
