【Ubuntu日常技巧】Ubuntu命令行设置系统时区、时间

最近折腾手机上安装Ubuntu,发现显示的时间不对,可惜当前的 Date and Time菜单中没法进行时间设置,而且其显示的为London地区的时间,故通过命令行修改之;

1、确定所在时区的编号

可以通过tzselect命令实现:

phablet@localhost:~$ tzselect
Please identify a location so that time zone rules can be set correctly.
Please select a continent or ocean.
 1) Africa
 2) Americas
 3) Antarctica
 4) Arctic Ocean
 5) Asia
 6) Atlantic Ocean
 7) Australia
 8) Europe
 9) Indian Ocean
10) Pacific Ocean
11) none - I want to specify the time zone using the Posix TZ format.
#? 5
Please select a country.
 1) Afghanistan          18) Israel            35) Palestine
 2) Armenia          19) Japan            36) Philippines
 3) Azerbaijan          20) Jordan            37) Qatar
 4) Bahrain          21) Kazakhstan        38) Russia
 5) Bangladesh          22) Korea (North)        39) Saudi Arabia
 6) Bhutan          23) Korea (South)        40) Singapore
 7) Brunei          24) Kuwait            41) Sri Lanka
 8) Cambodia          25) Kyrgyzstan        42) Syria
 9) China          26) Laos            43) Taiwan
10) Cyprus          27) Lebanon            44) Tajikistan
11) East Timor          28) Macau            45) Thailand
12) Georgia          29) Malaysia            46) Turkmenistan
13) Hong Kong          30) Mongolia            47) United Arab Emirates
14) India          31) Myanmar (Burma)        48) Uzbekistan
15) Indonesia          32) Nepal            49) Vietnam
16) Iran          33) Oman            50) Yemen
17) Iraq          34) Pakistan
#? 9
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

The following information has been given:

    China
    east China - Beijing, Guangdong, Shanghai, etc.

Therefore TZ='Asia/Shanghai' will be used.
Local time is now:    Sun Mar 24 11:54:21 CST 2013.
Universal Time is now:    Sun Mar 24 03:54:21 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

注意每次显示对于菜单后,在出现的 #?  后面 输入对于编号就可以了;最后一行为找到的时区信息;为: 

Asia/Shanghai

 

2、设置localtime

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

马上就可以发现时间已经改过来了;

更多时区信息可以在以下目录中去选取:

/usr/share/zoneinfo/
