I already sent them lines of the following form:

#------------------------------------------------------------------------------
# timezone:  file(1) magic for timezone data
#
# from Daniel Quinlan (quinlan at yggdrasil.com)
# this should work on Linux, SunOS, and maybe others
0	string	\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\1\0	timezone data
0	string	\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\2\0	timezone data
0	string  \0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\3\0	timezone data
0	string	\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\4\0	timezone data
0	string	\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\5\0	timezone data
0	string	\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\6\0	timezone data

which I snarfed from, I think, a Linux distribution (Debian?).

No guarantees that it's the best possible choice, although it does
manage to get the right answer on a SPARC/Solaris 2.5.1 system (on the
time zone data files that come with Solaris 2.5.1), except for the
"Eire" compiled file.
