Universal Time is now:  Wed May 25 06:53:40 UTC 2022.

提示

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

输入

timedatectl set-timezone 'Asia/Shanghai'
