请问这是什么意思？？？

Therefore TZ='Asia/Shanghai' will be used.
Local time is now:      Wed Jan 15 04:45:51 CST 2003.
Universal Time is now:  Tue Jan 14 20:45:51 UTC 2003.
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

后面说的是啥意思呀？？？

有两种方法来设置时区，一个是在设置文件里设置TZ环境变量，一个是用链接。我们一般都是用链接的。
