linux在安装的时候如果时区选择错误,可以在系统安装完成之后修改。系统时间运行着也会有偏差,需要对时间进行实时同步,本篇文章为大家讲解一下快速修改时区具体方法。
方法1: timedatectl set-timezone Asia/Shanghai
# timedatectl
Warning: Ignoring the TZ variable. Reading the system's time zone setting only.
Local time: Mon 2016-11-21 01:52:42 EST
Universal time: Mon 2016-11-21 06:52:42 UTC
RTC time: Mon 2016-11-21 06:52:42
Time zone: America/New_York (EST, -0500)
NTP enabled: n/a
NTP synchronized: no
RTC in local TZ: no
DST active: no
Last DST change: DST ended at
Sun 2016-11-06 01:59:59 EDT
Sun 2016-11-06 01:00:00 EST
Next DST change: DST begins (the clock jumps one hour forward) at
Sun 2017-03-12 01:59:59 EST
Sun 2017-03-12 03:00:00 EDT
设置时区为CST(东8区)
# timedatectl set-timezone Asia/Shanghai

Local time: Mon 2016-11-21 14:52:59 CST
Universal time: Mon 2016-11-21 06:52:59 UTC
RTC time: Mon 2016-11-21 06:52:59
Time zone: Asia/Shanghai (CST, +0800)
NTP enabled: n/a
NTP synchronized: no
RTC in local TZ: no
DST active: n/a
[root@localhost ~]#
方法2:TZ环境变量的方式
修改用户目录下的.bash_profile,在文件末尾追加:
TZ='Asia/Shanghai'; export TZ
推出登录后,重新登录,date命令可以查看效果。
