how to set LC_TIME in gnome?

[Dr. Michael J. Chudobiak]

How can I set LC_TIME=en_DK.UTF-8 for all users, to get a sensible ISO 
date format in most programs?

Setting /etc/locale.conf doesn't help:

[mjc@xena ~]$ more /etc/locale.conf
LANG=en_US.UTF-8
LC_TIME=en_DK.UTF-8

After rebooting, and launching a terminal in gnome-shell, LC_TIME is 
stuck at en_US:

[mjc@xena ~]$ locale | grep LC_TIME
LC_TIME="en_US.UTF-8"

Not sure. Is it normal for locale and localectl to report different 
values for LC_TIME?


[mjc@xena ~]$ localectl
    System Locale: LANG=en_US.UTF-8
                   LC_TIME=en_DK.UTF-8
        VC Keymap: us
       X11 Layout: us
        X11 Model: pc105+inet
      X11 Options: terminate:ctrl_alt_bksp,

[mjc@xena ~]$ locale
LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"

LC_ALL=

Dottore are you saying system wide settings doesn't apply to GNOME?

$ localectl set-locale LANG=en_US.UTF-8 LC_TIME=en_DK.UTF-8

$ localectl 
   System Locale: LANG=en_US.UTF-8
                  LC_TIME=en_DK.UTF-8
       VC Keymap: us
      X11 Layout: n/a

$ cat /etc/locale.conf 
LC_TIME=en_DK.UTF-8
LANG=en_US.UTF-8

$ man 1 localectl

IIUC, GNOME overrides the system-wide locale settings with it own values,
by default it's en_US.utf-8; there are two bits that affect the locale
settings in "gnome-control-center -> Region & Language", Language and
"Formats"; LC_TIME is affected by the "Formats" setting, which sets
the
value of the gsettings key 'org.gnome.system.locale region' (note that the
same value is set for LC_NUMERIC, LC_TIME, LC_MONETARY, LC_PAPER,
LC_MEASUREMENT).

You can change the default for all users using the following steps:
- Create
/usr/share/glib-2.0/schemas/org.gnome.system.locale.gschema.override and
put this in it:
[org.gnome.system.locale]
region='en_DK.utf8'

- As root execute:
/usr/bin/glib-compile-schemas /usr/share/glib-2.0/schemas

that's it, this should affect any newly created user account; and also any
existing user account where the user hasn't manually set the value of the
'org.gnome.system.locale region' key; of course setting the value of this
key manually will override the default value that you've just set via
org.gnome.system.locale.gschema.override.
