Wow, thank you! I had no idea about how zdump or zic worked.

This certainly looks accurate to the current book from my perspective.
And it's useful in general not just for glibc-2.3.2 vs glibc-2.3.6.
The zoneinfo files could be updated at any time, so it's good to know
how to generate them if you're not on the bleeding edge of glibc.

Chuck, I think it would be great if you could put these instructions
on the LFS wiki. Hmm, it doesn't appear to be as fleshed out as the
BLFS wiki. Let me get back to you on that...
