" Well, probably, but I couldn't find it.  I used information on how to change
" OpenSolaris, and, since it said "edit the file," I edited the file.


it's pretty well hidden, and quite possibly accidental that it's
publically accessible.

from "patch for US daylight savings time changes on Solaris2.5.1, 2.6,
2.7" on sunmanagers:

1. Details on timezone tables: 
"In the tz database's FTP distribution the code is in the file
tzcodeC.tar.gz, where C is the code's version; similarly, the data are
in tzdataD.tar.gz, where D is the data's version. The following shell
commands download these files to a GNU/Linux or similar host; see the
downloaded README file for what to do next.

wget 'ftp://elsie.nci.nih.gov/pub/tz*.tar.gz'
gzip -dc tzcode*.tar.gz | tar -xf -
gzip -dc tzdata*.tar.gz | tar -xf -
The code lets you compile the tz source files into machine-readable
binary files, one for each location. It also lets you read a tz binary
file and interpret time stamps for that location."

The above quote is from: 
http://www.twinsun.com/tz/tz-link.htm

The words "FTP distribution" in first sentence are link to:

ftp://elsie.nci.nih.gov/pub/

There's a file:

tzdata2007a.tar.gz

on that page that appears to have the timezone files. I am guessing this
may be what the respondent was thinking about. I'm not sure how to use
them, but hopefully that should be self evident on examination. 

2. Version-specific patch info:
Solaris 10 - I don't have the info yet
Solaris 9 - requires 113225-03 or later and 112874-33 or later
Solaris 8 - requires 109810-02 or later and 108993-52 or later
Solaris 7 - may be available online, though OS reaches EOL in 2007
Solaris 2.6 and earlier - will have to rebuild from timezone data tables
at www.nih.gov using "zic"
