The "tzfile.5.txt" file that's part of the and archives is your safest
bet for the binary files; the "zic.8.txt" file is your safest bet for
the source files.

Where can I find the specification for the format of the files within
the TZ database?

I am developing a Delphi (pascal) program to do time zone conversions,
using the TZ database.
