ubuntu设置时间显示为24小时制

对ubuntu默认的时间显示格式不太满意，查阅了相关资料进行修改为24小时制度，特此记录和分享给需要设置的网友

查看当前的timezone

root@jumpserver:~# timedatectl
               Local time: Sat 2024-03-23 12:45:53 UTC
           Universal time: Sat 2024-03-23 12:45:53 UTC
                 RTC time: Sat 2024-03-23 12:45:53
                Time zone: Etc/UTC (UTC, +0000)
System clock synchronized: yes
              NTP service: active
          RTC in local TZ: no
root@jumpserver:~#

列举可选的timezons

root@jumpserver:~# list-timezones

设置时区为上海

root@jumpserver:~# timedatectl set-timezone "Asia/Shanghai"
root@jumpserver:~#

设置时间为24小时制

• 设置完成后，需要退出SSH重新登录才会生效

root@jumpserver:~#  echo "LC_TIME=en_DK.UTF-8" >>/etc/default/locale
