1. 购买了VPS，CentOS系统，发现服务器时间与北京时间往往不一致，存在时差。

#? 9
Please select one of the following time zone regions.
1) Beijing Time
2) Xinjiang Time
#? 1

The following information has been given:

    China
    Beijing Time

Therefore TZ=‘Asia/Shanghai‘ will be used.
Local time is now:  Wed May 30 10:04:16 CST 2018.
Universal Time is now:  Wed May 30 02:04:16 UTC 2018.
Is the above information OK?
1) Yes
2) No
#? 1

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

1. 将TZ=‘Asia/Shanghai‘; export TZ这行添加到/etc/profile（所有用户生效）或者~/.bash_profile（当前用户生效）
2. 退出重新登录即可，也可执行source /etc/profile或source ~/.bash_profile立即生效
3. 这时候再执行date查看日期就可以发现时区改为北京时间啦。
