I'm in United States and am trying out Ubuntu. Very frustrated because all the dates and times are in non-sensical United States format:
Date = MM.DD.YY
Time = 12 hour format
I want ISO format to display system-wide:
Date = YYYY.MM.DD
Time = 24 hour format
Is this possible while keeping other United States locale stuff like $ (dollar), language, etc?
Partial answer.
You can set the various localization parameters on a parameter-per-parameter base using the LC_* environment variables. See man locale for a list. The one about date and time is called LC_TIME. You can test it by command line. For example, my default environment is en_IE:
$ date
Thu Nov 14 09:24:27 MST 2013
Seeing how date & time looks in Spanish:
$ LC_TIME=es_ES.UTF-8 date
jue nov 14 09:24:25 MST 2013
To see all of your installed locales you should do:
locale -a
You can add support for more languages/locales to your system.
When you find a suitable locale, you can add the variable systemwide in /etc/environment or for your user in ~/.pam_environment (see Where to declare environment variables?). For example, I have in my file:
$ cat ~/.pam_environment
LANGUAGE=en
LANG=en_US.UTF-8
LC_NUMERIC=en_IE.UTF-8
LC_TIME=en_IE.UTF-8
LC_MONETARY=en_IE.UTF-8
The answer is a partial one because I do not know if there is a locale that has the characteristics you want...
