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:      Thu Jul 11 13:33:27 CST 2019.
Universal Time is now:  Thu Jul 11 05:33:27 UTC 2019.
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 /bin/tzselect command in shell scripts:
Asia/Shanghai

 

 

更改时区

 

timedatectl set-timezone ‘Asia/Tokyo‘

更改后需要重新启动linux系统
