# 查看链接
ls -l /etc/localtime
---
lrwxrwxrwx 1 root root 27 Dec 10 12:59 /etc/localtime -> /usr/share/zoneinfo/Etc/UTC
---

# 系统的时区同时也被写入/etc/timezone文件：
cat /etc/timezone
---
UTC
---
# 使用timedatectl命令修改时区
timedatectl list-timezones
---
比如中国时区
Asia/Shanghai
---
# 设置具体时区
timedatectl set-timezone <your_time_zone>
---
e.g. timedatectl set-timezone Asia/Shanghai
---
# 运行命令，验证修改
timedatectl

# tips
# 设置为24小时显示
# 查看文件
cat /etc/default/locale
---
LANG=en_US.UTF-8
---
# 加入一行
echo "LC_TIME=en_DK.UTF-8" >> /etc/default/locale

# 重启机器
reboot
