命令行修改时区

     买的vps上运行程序的时候，老是报时区的错误，还真不知道如何在命令行下设置时区，百度了下，记录下方法，以备他日之需，下面看操作：

[root@279155 ~]# tzselect
Please identify a location so that time zone rules can be set correctly.

 3) Antarctica
 4) Arctic Ocean
 5) Asia
 6) Atlantic Ocean

 8) Europe

11) none - I want to specify the time zone using the Posix TZ format.

#? 9
（9，china）

Please select one of the following time zone regions.
1) east China - Beijing, Guangdong, Shanghai, etc.
2) Heilongjiang (except Mohe), Jilin
3) central China - Sichuan, Yunnan, Guangxi, Shaanxi, Guizhou, etc.
4) most of Tibet & Xinjiang
5) west Tibet & Xinjiang
#? 1

（这里选北京 1 ）
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 Apr 10 21:21:38 CST 2012.
Universal Time is now:  Tue Apr 10 13:21:38 UTC 2012.
Is the above information OK?
1) Yes
2) No
#? Yes
Please enter 1 for Yes, or 2 for 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
[root@279155 ~]#

   呵呵，还是很简单的，感兴趣，试验下吧
