[KDE 4.10.5/4.11.3] wrong timezone in system settings

sanjioh · 11-17-2013, 05:24 AM

Hello everybody,

I've noticed the following KDE's behaviour both in stock Slackware 14.1, that is with KDE 4.10.5, and with AlienBob's KDE 4.11.3.

In System Settings -> Date & Time -> Time Zone I can see:
Current local time zone: Europe/Rome (CEST).

In Italy we're currently in CET (winter time) timezone, but there's no way (to my knowledge so far) to get that in KDE.

Some details from the cli:

Code:

root@darkstar:~# date
Sun Nov 17 11:11:01 CET 2013
root@darkstar:~# hwclock
Sun 17 Nov 2013 11:11:05 AM CET  -0.206320 seconds
root@darkstar:~# md5sum /etc/localtime /usr/share/zoneinfo/Europe/Rome 
9828f4466350e4529d97c04e85554430  /etc/localtime
9828f4466350e4529d97c04e85554430  /usr/share/zoneinfo/Europe/Rome

Does this happen to someone else? Is there any open bug report about this, that you know about?

Screenshots attached.

Thanks!

Central European Time is UTC+1 during the winter and UTC+2 in the summer. The definition for Rome should do that automagically.
Central European Time changes to Central Europe Summer Time, CEST, Sunday 31 March 2013 01:00 GMT, then back to CET Sunday 27 October 2013 01:00 GMT.

The European NTP pool should know that. Put these lines in /etc/ntp.conf:
server 0.europe.pool.ntp.org
server 1.europe.pool.ntp.org
server 2.europe.pool.ntp.org
server 3.europe.pool.ntp.org

I don't know why your system thinks it is still in CEST. Might try deleting /etc/localtime, then copy /usr/share/zoneinfo/Europe/Rome to /etc/localtime. Add a softlink:
`ln -s /usr/share/zoneinfo/Europe/Rome localtime-copied-from` for future reference.

/etc/rc.d/rc.ntpd stop
/usr/sbin/ntpdate 3.europe.pool.ntp.org
/sbin/hwclock --systohc
/etc/rc.d/rc.ntpd start

(all those as root)

Hi, thanks for your answer.
Actually, just KDE thinks it's still in CEST: if you look at the CLI commands I included, the rest of the system is fine with the new timezone.
I'm at work now and can't test your suggestions, I will as soon as I can; I really doubt that that's the solution, though.

Thanks again!

Filed a bug report to KDE: https://bugs.kde.org/show_bug.cgi?id=327734

Hello, in my system settings the time zone is Berlin and it works fine.

I've followed hpfeil's steps to to avail. Still CEST in KDE and CET in the CLI.
@guanx: Berlin gives CEST as well in KDE. Just to know, what do you get if you set Rome?

Thanks!

Rome also gives UTC+1, same as Berlin.

Did you restart KDE after 27.Oct.2013 ? If not, try restart KDE and see.
