Yum And Yumex Change System Time
greetings,
each and every time i run yum or yumex, system time is advanced by 5 hours.
this has gone on thru several updates, maybe even upgrades.
CentOS = 6.6 current yum = 3.2.29
yumex = 3.0.5
for awhile, i did not mind resetting clock when i noticed it off.
now, it is a pita because when i forget, emails and what ever else i am doing get wrong time stamps.
i have searched for problem/solution, but none found. or i missed it reading search page.
most appreciative if anyone knows of a solution.
tia.

Hmmm, that’s a really strange problem.
yum really doesn’t have anything to do with your system clock. It just installs, updates and removes packages. I’ve never used ‘yumex’
but i assume it just runs yum behind the scenes.
The only thing I can think of is that your system is installing a tzdata package and failing, and somehow you’re replacing the time zone with the original each time you fix it. Since your date is listed as
-0500, it would seem likely that it is related.
I agree, so my questions are:
– what is your TZ?
– what does “[/bin/]date” show?
– what does your hardware clock: “/sbin/hwclock –show” report?
[need to be root to use that command]
– is your /etc/localtime file a standalone file or a symlink
to /usr/share/zoneinfo/… ?
– if a symlink, to what file?
– what is the timestamp on the localtime (or what it’s
symlinked to) file?
– what does “zdump -v /etc/localtime” return ? i.e., is it for
the correct TZ?
Richard, thank you for your response.

u.s.a. ‘central time zone’ – currently on ‘daylight savings time’.

currently it is a copy of file from /usr/share/zoneinfo/ on advice from a post to this list when i had problem getting correct time to show in clock in panel.
see above answer.

so, yes. i am in ‘central time zone’ observing ‘daylight savings time’.

cussing and using “System Settings > Date & Time” to make change after i enter root user password. :-\
thanks again for you response.
<<>>
if there were no strange problems, i would have no problems. ;-)
i would think not, but something is happening.
time change happens even when there is no tzdata package.
-0500 = utc -0600 daylight savings time = utc -0500
thank you for responding.
Edit the file:
/etc/sysconfig/clock
make sure to set:
ZONE=”America/Chicago”
then copy /usr/share/zoneinfo/America/Chicago to /etc/localtime
Run the time tool and make sure that “System clock uses UTC” is NOT checked
THAT’s the option Anaconda also presents, that I was thinking of. :)
<<>>
it was;
ZONE=”Etc/UTC”
it is now.
ZONE=”America/Chicago”
done.
if by ‘time tool’ you mean “System Settings > Date & Time”, there is no “System clock uses UTC”.
i ran ‘yumex’ to pull in some progs, ‘tzdata-2015e-1.el6.noarch.rpm’
was updated 2015-0621, so i could not pull it.
closed ‘yumex’ no change in system time in panel. rebooted, still OK.
1 problem left. :-(
when i started kde after rebooting, i ran the ‘hwclock’ and ‘zdump’
checks, all compared to before. but…
time stamp showing in konqueror is CST, not CDT.
when i mouse over clock in panel, ‘Chicago’ and ‘UTC’ times show correctly, ie,
Chicago 21:30, Wednesday 24 June 2015
UTC 02:30, Thursday 25 June 2015
‘Chicago’ is CDT, -0500 hrs, yet, knoqueror stamps CST.
what would be causing konqueror to be time stamping CST instead of CDT?
how to correct?
