前言如果你的 Linux 系统时区配置不正确,必需要手动调整到正确的当地时区。NTP 对时间的同步处理只计算当地时间与 UTC 时间的偏移量,因此配置一个 NTP 对时间进行同步并不能解决时区不正确的问题。所以大家在用了国外云计算服务商如 Microsoft Azure 或其它 VPS、虚拟机时,需要注意是否与中国大陆的时区一致。
教程查看Linux当前时区
你可以使用如下命令非常容易地就查看到 Linux 系统的当前时区:
root@mcheng:~# dateMon 09 May 2022 02:24:05 AM EDTroot@mcheng:~# ls -l /etc/localtimelrwxrwxrwx 1 root root 30 Aug 16 2021 /etc/localtime -> /usr/share/zoneinfo/US/Easternroot@mcheng:~# dateMon 09 May 2022 02:24:05 AM EDTroot@mcheng:~# ls -l /etc/localtimelrwxrwxrwx 1 root root 30 Aug 16 2021 /etc/localtime -> /usr/share/zoneinfo/US/Easternroot@mcheng:~# dateMon 09 May 2022 02:24:05 AM EDTroot@mcheng:~# ls -l /etc/localtimelrwxrwxrwx 1 root root 30 Aug 16 2021 /etc/localtime -> /usr/share/zoneinfo/US/Eastern获取时区TZ值
要更改 Linux 系统时区首先得获知你所当地时区的 TZ 值,使用 tzselect 命令即可查看并选择已安装的时区文件。
执行 tzselect 命令:
root@DMIT-SIeyeophVm:~# tzselectPlease identify a location so that time zone rules can be set correctly.Please select a continent, ocean, "coord", or "TZ".1) Africa 7) Europe2) Americas 8) Indian Ocean3) Antarctica 9) Pacific Ocean4) Asia 10) coord - I want to use geographical coordinates.5) Atlantic Ocean 11) TZ - I want to specify the time zone using the Posix TZ format.6) Australia#?

TZ='Asia/Shanghai'; export TZTZ='Asia/Shanghai'; export TZTZ='Asia/Shanghai'; export TZ执行完成之后需要重新登录系统或刷新 ~/.bashrc 生效:
ource ~/.bashrcource ~/.bashrcource ~/.bashrc检验系统当前时间:
root@DMIT-SIeyeophVm:~# dateMon 09 May 2022 02:28:56 PM CSTroot@DMIT-SIeyeophVm:~# dateMon 09 May 2022 02:28:56 PM CSTroot@DMIT-SIeyeophVm:~# dateMon 09 May 2022 02:28:56 PM CST然后在执行:
sudo rm -f /etc/localtimesudo ln -s /usr/share/zoneinfo/Asia/Shanghai /etc/localtimesudo rm -f /etc/localtimesudo ln -s /usr/share/zoneinfo/Asia/Shanghai /etc/localtimesudo rm -f /etc/localtimesudo ln -s /usr/share/zoneinfo/Asia/Shanghai /etc/localtime使用Systemd更改Linux系统时区
如果你使用的 Linux 系统使用 Systemd,还可以使用 timedatectl 命令来更改 Linux 系统范围的时区。在 Systemd 下有一个名为 systemd-timedated 的系统服务负责调整系统时钟和时区,我们可以使用 timedatectl 命令对此系统服务进行配置:
[root@lax ~]# sudo timedatectl set-timezone 'Asia/Shanghai'[root@lax ~]# datetimecal Local time: Mon 2022-05-09 15:10:51 CST Universal time: Mon 2022-05-09 07:10:51 UTC RTC time: Mon 2022-05-09 07:08:53 Time zone: Asia/Shanghai (CST, +0800) NTP enabled: yesNTP synchronized: yes RTC in local TZ: no DST active: n/a[root@lax ~]# dateMon May 9 15:11:14 CST 2022[root@lax ~]# sudo timedatectl set-timezone 'Asia/Shanghai'[root@lax ~]# datetimecal Local time: Mon 2022-05-09 15:10:51 CST Universal time: Mon 2022-05-09 07:10:51 UTC RTC time: Mon 2022-05-09 07:08:53 Time zone: Asia/Shanghai (CST, +0800) NTP enabled: yesNTP synchronized: yes RTC in local TZ: no DST active: n/a[root@lax ~]# dateMon May 9 15:11:14 CST 2022[root@lax ~]# sudo timedatectl set-timezone 'Asia/Shanghai'[root@lax ~]# datetimecal Local time: Mon 2022-05-09 15:10:51 CST Universal time: Mon 2022-05-09 07:10:51 UTC RTC time: Mon 2022-05-09 07:08:53 Time zone: Asia/Shanghai (CST, +0800) NTP enabled: yesNTP synchronized: yes RTC in local TZ: no DST active: n/a[root@lax ~]# dateMon May 9 15:11:14 CST 2022[免费VPS]历史优惠活动内容
