You should update tzdata.  The current version is tzdata-2007h-1.
Then you can check if the time change is correctly set up by running
this command:

/usr/sbin/zdump -v CST6CDT | grep 2007

The output will be similar to:

CST6CDT  Sun Mar 11 07:59:59 2007 UTC = Sun Mar 11 01:59:59 2007 CST
isdst=0 gmtoff=-21600
CST6CDT  Sun Mar 11 08:00:00 2007 UTC = Sun Mar 11 03:00:00 2007 CDT
isdst=1 gmtoff=-18000
CST6CDT  Sun Nov  4 06:59:59 2007 UTC = Sun Nov  4 01:59:59 2007 CDT
isdst=1 gmtoff=-18000
CST6CDT  Sun Nov  4 07:00:00 2007 UTC = Sun Nov  4 01:00:00 2007 CST
isdst=0 gmtoff=-21600

Hope this helps,
