It's the same way changing the language… you're expected to reboot because there's no simple way of ensuring everything will update at runtime.
I assume all we need is a new setting. Support for this is up to the apps. ** Changed in: ubuntu-ui-toolkit (Ubuntu) Status: New => Invalid ** Changed in: libc (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to ubuntu-ui-toolkit in Ubuntu. https://bugs.launchpad.net/bugs/1392699 Title: Can't change locale settings (e.g. language, 12/24-hour time, date format) independently Status in “libc” package in Ubuntu: Invalid Status in “ubuntu-system-settings” package in Ubuntu: Confirmed Status in “ubuntu-ui-toolkit” package in Ubuntu: Invalid Bug description: A. Try to use US English, but with all apps using 24-hour instead of 12-hour time. Or: B. Try to use UK English, but with all apps using YYYY-MM-DD date format. What happens: You can't. What should happen: You can. Since Ubuntu has existed, it has used the GNU locale system. This system assumes that every single person using a particular locale wants exactly the same settings for time display, date display, currency display, alphabetizing, and number formatting. <http://www.gnu.org/software/libc/manual/html_node/Effects-of- Locale.html> Windows, Mac OS, and (to a lesser extent) iOS have always been more flexible: setting a locale sets appropriate defaults for these settings, but you can also change them individually. Ubuntu should do the same. This might involve changing the locale system itself, or it might involve changing all relevant toolkits so that they ignore the locale system when appropriate. It would also involve adding settings in System Settings to customize the individual locale details.
