tzselect号令用于选择时区。要留意的是tzselect只是帮我们把选择的时区显示出来，其实不会现实生效，也就是说它仅仅告诉我们怎么样去设置情况变量TZ。（TZ = Time Zone）（The
tzselect
program asks the user for information about the current location, and outputs the resulting time zone description to standard output。
The output is suitable as a value for the TZ environment variable。 All interaction with the user is done via standard input and standard error。
）若是你要永久更改时区，根据tzselect号令提醒的信息，在。profile或者/etc/profile中设置准确的TZ情况变量并导出。还有别的一种更改时区的办法就是间接更改系统设置装备摆设文件/etc/sysconfig/clock，然后修改符号链接/etc/locatime对应的文件，详见示例三。

The following information has been given:

Therefore TZ='Asia/Shanghai' will be used。
Local time is now:
Mon Dec
6 09:40:35 CST 2010。
Universal Time is now:
Mon Dec
6 01:40:35 UTC 2010。

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
[root@new55 ~]#
如今要做的工作就是根据提醒，把
TZ='Asia/Shanghai'; export TZ
添加到。
profile中（bash对应加到。bash_profile）。
