tzselect
将 UTC 改成CST
1. # tzselect
依次输入数字  5 9 1 1 设置为 China Standard Timezone

You can make this change permanent for yourself by appending the line
TZ='Asia/Beijing'; export TZ
to the file '.profile' in your home directory; then log out and log in again.

vi /etc/profile
添加  TZ='Asia/Beijing'; export TZ，之后 souce /etc/profile，使之生效
也可以一句话写完 ：
echo "TZ='Asia/Beijing'; export TZ" >> /etc/profile; source /etc/profile
