this worked for linux.

I built the tools that come in the code bundle and:
#  code/zdump -v CST6CDT | grep 2007
CST6CDT  Sun Mar 11 07:59:59 2007 UTC = Sun Mar 11 01:59:59 2007 CST
isdst=0
CST6CDT  Sun Mar 11 08:00:00 2007 UTC = Sun Mar 11 03:00:00 2007 CDT
isdst=1
CST6CDT  Sun Nov  4 06:59:59 2007 UTC = Sun Nov  4 01:59:59 2007 CDT
isdst=1
CST6CDT  Sun Nov  4 07:00:00 2007 UTC = Sun Nov  4 01:00:00 2007 CST
isdst=0

#  zdump -v CST6CDT | grep 2007
CST6CDT  Wed Jan 10 23:23:36 2007 GMT = Wed Jan 10 17:23:36 2007 CST
isdst=0
CST6CDT  Sun Apr  1 07:59:59 2007 GMT = Sun Apr  1 01:59:59 2007 CST
isdst=0
CST6CDT  Sun Apr  1 08:00:00 2007 GMT = Sun Apr  1 03:00:00 2007 CDT
isdst=1
CST6CDT  Sun Oct 28 06:59:59 2007 GMT = Sun Oct 28 01:59:59 2007 CDT
isdst=1
CST6CDT  Sun Oct 28 07:00:00 2007 GMT = Sun Oct 28 01:00:00 2007 CST
isdst=0

They work, where Sun's doesn't, though for, say Chicago:
 #  zdump -v America/Chicago | grep 2007
America/Chicago  Wed Jan 10 23:25:11 2007 GMT = Wed Jan 10 17:25:11 2007
CST isdst=0
America/Chicago  Sun Mar 11 07:59:59 2007 GMT = Sun Mar 11 01:59:59 2007
CST isdst=0
America/Chicago  Sun Mar 11 08:00:00 2007 GMT = Sun Mar 11 03:00:00 2007
CDT isdst=1
America/Chicago  Sun Nov  4 06:59:59 2007 GMT = Sun Nov  4 01:59:59 2007
CDT isdst=1
America/Chicago  Sun Nov  4 07:00:00 2007 GMT = Sun Nov  4 01:00:00 2007
CST isdst=0

it does. So I did a truss on zdump for CST6CDT and it never opens a
zoneinfo file. It just calls "time()". But it does open the zoneinfo file
for America/Chicago.

appears to be some patches for it.

If  it's not  on  fire  it's  a  software  problem.
