[CentOS] Strange issue with system time being off

Hi all,

I am having an issue with some older CentOS 5.3 servers. Every time the server boots, it gives the error "Cannot access the hardware clock by any known method", and then promptly sets the time 5 hours behind the hardware clock, down to the second.

After the system is up. "hwclock" works fine. hwclock --debug does not show any error at all.

The hardware clock is configured in local time. /etc/sysconfig/clock is set to UTC=false and ZONE="America/Chicago". /etc/localtime is a copy of Chicago's zone file. /etc/adjtime is configured with "LOCAL" as the third row. I am at a loss as to what is causing this.

Any assistance is appreciated! Thanks!
