you told it that the system clock is set to UTC ... it sets the time
based on that when it boots up.

But, your system clock is NOT really set to UTC, it is set to CST.  So
you lied :D

That means it is going to shift your CST value by the amount of hours
you are away from CST as a correction, since you told it that the
hardware clock is set to UTC.

What you need to do to fix it is edit "/etc/sysconfig/clock" and if
there is a UTC=true, change it to UTC=false.
