 It's not what I would call, non interactive, or even
elegant, but below  is what I have done on some
systems. On others, I just installed a copy of the
newly created /etc/localtime file.

 Maybe it will be useful to you.

cd /usr/src/share/zoneinfo
tar -zxvf tzdata2007a.tar.gz
make install

cp -f /usr/share/zoneinfo/America/Los_Angeles
chmod 444 /etc/localtime
