Description of problem:
I cannot set the time on any clock on my computer and have it "stick". Every
time the computer is rebooted, something sets the time to 4 hours earlier. If I
set the clock in the system BIOS at boot, by the time I login, the system rtc
and hwclock are 4 hours behind. If I set the time using date, or hwclock
--set, hwclock --systohc, timeconfig, or redhat-config-time, it doesnt keep.
Upon reboot, it is 4 hours behind. If I do nothing but reboot again, I loose
another 4 hours, and so on, and so on.....
My timzone is EDT, is this a coincidence? EDT is 4 hours behind UTC.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.set time (any method)
Actual Results: time is 4 hours behind
Expected Results: Time should be correct. The system should not continually
adjust 4 hours off of the correct time.
Am I nuts? I have to believe I am missing something obvious, and if that is the
case, I apologize. I have spent 2 days searching for info on setting the time
on a linux system, and nothing I've found works. I have setup many linux
machines, servers and workstations, since RedHat 4 and never had any problem
quite like this. I am setting the serverity to security because an incorrect
clock has all kinds of security issues for me. Feel free to change it if you
What does your /etc/sysconfig/clock say? What is /etc/localtime?
/etc/localtime is a link to -> /usr/share/zoneinfo/America/Detroit
and /etc/sysconfig/clock is
Is /usr a separate filesystem? If so, make sure /etc/localtime is a copy, and
not a symlink.
You ought to put this on the RHCE exam :)
That fixed it. The obvoius question, why does a link get made to a filesystem
not availabe when the system syncs the clocks? If it matters, I upgraded from
RH8, but I think that was a clean install. If not, 7.3 before that was the
clean install. I don't think I could have copied an old localtime from
anywhere. AFAIK, this is the result of just regular installation/upgrade and
setting the time with the provided tools. I'd be happy to provide more info if
this seems to be some rare condition on my system.
Anyway, thank you very much. I can start growing my hair back.
It's a bug in redhat-config-date, I believe.
This is a dupe of bug #91228.
