#?     -------这里选9   中国

Please select one of the following time zone regions.

) Beijing Time

) Xinjiang Time

#?     这里选1    北京

 

The following information has been given:

    China

    Beijing Time

Therefore TZ='Asia/Shanghai' will be used.

Local time is now:    Wed Aug  :: CST .

Universal Time is now:    Wed Aug  :: UTC .

Is the above information OK?

) Yes

) No

#?      这里选1   yes确认保存



You can make this change permanent for yourself by appending the line

    TZ='Asia/Shanghai'; export TZ

to the file '.profile' in your home directory; then log out and log in again.

Here is that TZ value again, this time on standard output so that you

can use the /usr/bin/tzselect command in shell scripts:

Asia/Shanghai

[root@master conf]# date

Wed Aug  :: PDT 

改到这里此时时区还是PDT，需要修改profile文件

[root@master conf]# vim /etc/profile

 # time

 TZ='Asia/Shanghai'

 export TZ

[root@master conf]# source /etc/profile

此时时区已经变为CST

[root@master conf]# date

Wed Aug  :: CST 

方法2： 修改Linux系统时间EDT改为CST  文章链接：https://www.cnblogs.com/senlinyang/p/10978506.html

今天发现一台服务器时间比北京时间慢 12 个小时，使用 date 命令后发现是：

2019年 06月 04日 星期二 :: EDT

EDT 时间即美国东部时间。

这里要改为北京时间即可：

mv /etc/localtime /etc/localtime.bak

ln -s /usr/share/zoneinfo/Asia/Shanghai  /etc/localtime

然后再次 date 查看日期：

2019年 06月 05日 星期三 :: CST

时间就变成北京时间了.
