ubuntu系统修改时区-linux_第3张图片

The following information has been given:

    China

    east China - Beijing, Guangdong, Shanghai, etc.

Therefore TZ='Asia/Shanghai' will be used.

Local time is now:   Tue Dec 17 18:22:10 CST 2013.

Universal Time is now: Tue Dec 17 10:22:10 UTC 2013.

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

6.复制文件到/etc目录下

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

7.更新时间

1

sudo ntpdate time.windows.com

8.修改时间以后,修改硬件CMOS的时间

sudo hwclock --systohc

 9.设置环境变量

echo 'Asia/Shanghai' >/etc/timezone
