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.
