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.
Selected time is now: Mon Jan 4 23:23:11 CST 2021.
Universal Time is now: Mon Jan 4 15:23:11 UTC 2021.
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

  • 复制文件到/etc目录下
root@lbs-virtual-machine:~# cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
  • 再次查看时区,是否东八区
root@lbs-virtual-machine:~# date -R
