time didn't change for dst

[Dave Martini 1]

I have this tzdata pachage installed but my time on my RHEL 4 server but 
my servers time still shows the incorrect time.
Is there something else I need to do?

# rpm -qa |grep tzd
tzdata-2007c-1.el4

zdump -v /etc/localtime | grep 2007
/etc/localtime  Sun Mar 11 09:59:59 2007 UTC = Sun Mar 11 01:59:59 2007 
PST isdst=0 gmtoff=-28800
/etc/localtime  Sun Mar 11 10:00:00 2007 UTC = Sun Mar 11 03:00:00 2007 
PDT isdst=1 gmtoff=-25200
/etc/localtime  Sun Nov  4 08:59:59 2007 UTC = Sun Nov  4 01:59:59 2007 
PDT isdst=1 gmtoff=-25200
/etc/localtime  Sun Nov  4 09:00:00 2007 UTC = Sun Nov  4 01:00:00 2007 
PST isdst=0 gmtoff=-28800

Thanks.
Dave.
