The following information has been given:                                       
                                                                                
        China                                                                   

        Beijing Time                                

Therefore TZ='Asia/Shanghai' will be used.                                      
Local time is now:      Fri May 24 13:55:24 CST 2019.                           
Universal Time is now:  Fri May 24 05:55:24 UTC 2019.                           
Is the above information OK?                                                    

1) Yes                                                                          
2) No                                                                           

#?  1    //选择1确定

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

cp /usr/share/zoneinfo/Asia/Shanghai  /etc/localtime
