At this point we have to assume that the problem could be anywhere, in hardware
or software, and we have to dig deeper.

Please answer these questions:
- do you have other OSs on your machine (Win, FreeBSD, etc) ?
  Do you observe the same faulty clock/time behavior in them ?
  How is your Win configured ? To local or UTC time ?
- do you run Fedora in virtualized environment ?
- is your Fedora system up-to-date ?
  Just do it:
  # yum check-update
  # yum update
- is your kernel original (Fedora's) or customized ?
- what Fedora desktop manager do you have (GNOME, KDE, etc) ?
- do you get that same or another error message when you try to change system
  clock as below ? 
  assuming GNOME:
  System - Admin - Date & Time
  Time Zone tab
  at bottom you see: System clock uses UTC
  normally it should be Off (cleared).
  check it off (turn it On) and press OK
  any error message ?
  did it accept ? if yes, restore it to original Off state.
- reboot your machine, go into BIOS, make sure your CMOS clock is set to your
  local date and time
- save (!) BIOS settings and restart
- what time is shown on your desktop panel ? print it for us ...
  Is it approx equal to the time you set in BIOS, local and correct ?
- Now do not make any changes to your clock/time while we are testing !
- give us display of (unedited; as root to simplify):
  Open your gnome terminal or other xterm.
  Do these entries in one session so we can compare the date/times.
  # uname -a
  # cat /etc/grub.conf
  # rpm -V gnome-panel
  # rpm -V system-config-date
  # yum list installed "*tzdata*"
  # rpm -V tzdata
  # tail /var/log/messages
  # date
  Is that above your local and correct date and time ? 

  # ls -al /dev/rtc*
  # dmesg | grep -i rtc
  # cat /proc/devices | grep -i rtc
  # ls -al /etc/adjtime
  # cat /etc/adjtime
  # hwclock --debug --show
  # grep -ir "hwclock" /etc/init.d/

  # cat /etc/sysconfig/clock
  # ls -al /etc/localtime

Post it to mailing list now. We will take a look at it.

In the meantime, look at this since your last boot
# less /var/log/messages

search for recent date and time and locate line starting with this:
  Linux version 2.6.35.9-    271 64.fc14.i686
(mockbuild@xxxxxxxxxxxxxxxxxxxxxxxxxxxxx) (gcc version 4.5.    271 1 20100924
(Red Hat 4.5.1-4) (GCC) ) #1 SMP Fri Dec 3 12:35:42 UTC 2010

and see if there are any error messages you think may be related to
time/date/rtc/clock and so on ?
Let us know if anything catches your attention.

JB
