Use
a 24-hour clock in Ubuntu

This note applies to:

Ubuntu Lucid 10.04

Mozilla Thunderbird 3.0.8

Mozilla Lightning 1.0b1

I am a fervent user of the 24-hour clock. However, when I install a new platform, I often accept the default locale of en_US.UTF8. In general, I do not mind this locale. However, applications such as Thunderbird use the locale to adjust the display of various
elements, including time. It affects also plug-ins such as Lightning.

This note is a receipt that changes the default time display from 12-hour clock to 24-hour clock.

Edit the default locale file

sudo gedit /etc/default/locale

Add the following line at the end of the default local file:

LC_TIME="en_DK.UTF-8"

Reboot the computer… (yeah, it is lame)

sudo reboot

That’s it! From then on, applications that follow the locale will display the time in 24-hour clock format.

To verify that you successfully changed the locale, use the locale command:

locale

The entry LC_TIME=en_DK.UTF-8 should
be displayed.

BTW：如果你只是想设置文件浏览器中的时间显示格式，那么按照如下操作即可：

For nautilus file manager, the date setting format is here:

Menu > Edit > Preferences > Display tab
