[CentOS] Strange issue with system time being off

Thanks, I tried again, rebooted, still 5 hours off slow. The second I
do "hwclock --hctosys" the time is fine. That's silly to have to do
that though, I feel like I am missing a configuration parameter
somewhere.



[root at nod705 ~]# date
Thu Aug  9 10:06:36 CDT 2012

[root at nod705 ~]# hwclock
Thu 09 Aug 2012 03:06:39 PM CDT  -0.437183 seconds


[root at nod705 ~]# cat /etc/sysconfig/clock
# The ZONE parameter is only evaluated by system-config-date.
# The timezone of the system is defined by the contents of /etc/localtime.
ZONE="America/Chicago"
UTC=false
ARC=false



[root at nod705 ~]# cat /etc/adjtime
0.0     0       0.0
0
LOCAL
