I think the latter, unless you want to use Java
<http://www.bmsi.com/java/#TZ>.

Jonathan Lennox proposed a C API in
http://www.cl.cam.ac.uk/~mgk25/time/c/proposal-lennox.txt
I vaguely recall that something got implemented; perhaps
you can consult the archive of the tz mailing list.

GNU/Linux (i.e., glibc) and tzcode are both reasonable.  Neither is
bug-free.  GNU/Linux currently has some problems with negative time
stamps; tzcode with large 64-bit time_t values -- choose your poison.
GNU/Linux is LPGLed and is probably more widely used; tzcode is public
domain.
