#? 9

 

4、选择北京时间

Please select one of the following time zone regions.
1) Beijing Time
2) Xinjiang Time
#? 1

 

5、选Yes

The following information has been given:

    China
    Beijing Time

Therefore TZ=Asia/Shanghai will be used.
Local time is now:    Thu May 18 15:43:26 CST 2017.
Universal Time is now:    Thu May 18 07:43:26 UTC 2017.
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

 

方式1:在用户目录的.profile文件中加入一行下列内容,然后source ~/.profile使其生效

export TZ=Asia/Shanghai

 

方式2:复制相应的时区文件到/etc目录下

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

 

6、同步时间

[email protected]:~$ sudo ntpdate pool.ntp.org
18 May 15:53:12 ntpdate[26982]: adjust time server 193.228.143.14 offset -0.154279 sec
