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 at x86-11.phx2.fedoraproject.org) (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.
