Well, the principal GUI way to change language and locale is via System Settings -> Language Support.
https://help.ubuntu.com/stable/ubuntu-help/session-formats.html I could have suggested you to switch to the Regional Formats tab there and select something else but "English (United States)". But then also the number format, currency and other stuff had been affected. The environment above shows that you have selected English (US) as the display language and indicates that you are located in the US, so I assumed that you preferred a minimum change. Bottom line is: Things like date and time format is generally locale dependent with a few exceptions where you can control it in respective application, and the time format of the en_US.UTF-8 locale is 12 hour with AM/PM. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to unity-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1652243 Title: Times for other locations shows up as AM & PM not "24-hour time" Status in unity-control-center package in Ubuntu: Invalid Bug description: When you select "24-hour time" in Time & Date --> Clock.
