One of them lists UTC; the other list US/Eastern. I'm trying to get the machine to think in UTC but present my user experience in US/Eastern -- and another's experience in US/Pacific, or any other time zone. So far, the results have been mixed :-(
Mixed in what regard? UTC means the system's hardware clock (which you can control via the BIOS) is running in UTC mode, i.e. Zulu time == +-0 hrs. The TIMEZONE describes your local environment which in your case is Zulu time +6 hrs. US/Pacific would be Zulu time +9 hrs. Does running "date" produce your local time? Here are some examples how you can control date's output (I have added the output on my local system as an example): : Print Coordinated Universal Time (UTC) $ date -u Thu Sep 10 16:48:17 UTC 2020 : Print current time at your local area, i.e. your TIMEZONE: $ date Thu Sep 10 18:48:27 CEST 2020 : Print current time at another area: $ env TZ=US/Pacific date Thu Sep 10 09:48:37 PDT 2020
Thanks again!

But those date commands print the date in a user's environment. Which can be changed as you demonstrate. And which can be different for every user. /etc/sysconfig/clock presumably says something about the system environment. Something different. Quite what, I'm not sure, TBH. FWIW on my system: $ cat /etc/sysconfig/clock TIMEZONE="Europe/London" DEFAULT_TIMEZONE="US/Eastern" Now why would I in the UK have a line that says something about US time on a system built in Europe?

No, it doesn't. It only defines the default for users. The system clock in every Unix and Linux machine is a "variant" of UTC time. Actually, it simply counts seconds since the Epoch, a point in time. When the time is printed, the time is converted to whatever that user local time is. <https://en.wikipedia.org/wiki/Unix_time>
FWIW on my system:
$ cat /etc/sysconfig/clock TIMEZONE="Europe/London" DEFAULT_TIMEZONE="US/Eastern"
Now why would I in the UK have a line that says something about US time on a system built in Europe?
I think that something in that file is obsolete. On a newly installed Leap 15.2 machine, I get: /media/ExtMain/etc/sysconfig/clock DEFAULT_TIMEZONE="US/Eastern" Which I know is wrong, I definitely said in YaST during installation to use Spain/Madrid time, ie, CEST. /etc/localtime is a symlink that points to /usr/share/zoneinfo/Europe/Madrid and that is what the system actually uses. I think you found a bug. -- Cheers / Saludos, Carlos E. R. (from 15.1 x86_64 at Telcontar)

The files are not related, except that they deal with time settings. "/etc/adjtime" is for the hardware clock settings.

date is run in a user's environment, so can't have anything to do with a systemwide file in /etc, I suggest.

It doesn't take much bravery. But it would only prove that the file is not used by anything that I am doing. I checked out files in "/etc/sysconfig" using: cd /etc/sysconfig for file in * do rpm --query --file $file && echo FILE=$file done It turns out that most files there are not owned by any package.

All files in /etc/sysconfig come from /usr/share/fillup-templates/ with a "sysconfig." prefix (on older systems it was /var/adm/fillup-templates/) and they are generated during installation of their packages. So you could find out where those files belong to by running "rpm -qf /usr/share/fillup-templates/sysconfig.*". BTW, there is no "sysconfig.clock" in /usr/share/fillup-templates/ anymore, so it really is a zombie from older installations. Interestingly I installed my 15.2 system freshly during its Beta phase, so it's surprising that the /etc/sysconfig/clock file is still around... Cheers. l8er manfred

It is written by YaST country module with US/Eastern being default if there is no mapping from current language code to timezone. It is really "default"; current sytsem timezone is taken from /etc/localtime.

Sorry, but exactly which module do you mean? If I type 'country' into the search box in the YaST GUI it shows me 'System Keyboard Layout' and 'Language'. The first doesn't seem relevant and the second explicitly says that 'These settings are written into the file /etc/sysconfig/language.' -- To unsubscribe, e-mail: opensuse-support+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-support+owner@opensuse.org
