1、使timedatectl 命令

root@debian8204:~# timedatectl
               Local time: Tue 2025-08-26 11:11:29 CST
           Universal time: Tue 2025-08-26 03:11:29 UTC
                 RTC time: Tue 2025-08-26 03:11:29
                Time zone: Asia/Shanghai (CST, +0800)
System clock synchronized: yes
              NTP service: active
          RTC in local TZ: no

2、查/etc/timezone 文件(debian/ubuntu)

root@debian8204:~# cat /etc/timezone 
Asia/Shanghai

3、查看软链接文件(通用方法)

root@debian8204:~# ls -l /etc/localtime 
lrwxrwxrwx 1 root root 33 Oct 20  2023 /etc/localtime -> /usr/share/zoneinfo/Asia/Shanghai

4、使用date命令

root@debian8204:~# date
Tue Aug 26 11:16:36 AM CST 2025
root@debian8204:~# date +"%Z %z"
CST +0800

(显示时区缩写和UTC偏移量)

常见时区格式:

  •  Asia/Shanghai(中国标准时间,CST,UTC+8)

  •  America/New_York(美国东部时间,UTC-5/UTC-4)

  • Europe/London(格林尼治时间,UTC+0/UTC+1)

如果需要修改时区,可以使用:

sudo timedatectl set-timezone Asia/Shanghai
