[Linux] 查看并修改时区

作者:互联网

今天拿到了一台亚洲区的azure云服务器,使用date查看时间的时候发现时间不对。使用date -R的时候显示的是:

Mon, 19 Jul 2021 07:56:51 +0000

发现时区不对,于是乎开始修改时区操作:

1、使用tzselect生成想要的时区配置

也就是最终生成:TZ='Asia/Shanghai'; export TZ ,具体一步步操作如下参照

[aroot@APP2 Asia]$ tzselect
Please identify a location so that time zone rules can be set correctly.
Please select a continent, ocean, "coord", or "TZ".
 1) Africa
 2) Americas
 3) Antarctica
 4) Asia
 5) Atlantic Ocean
 6) Australia
 7) Europe
 8) Indian Ocean
 9) Pacific Ocean
10) coord - I want to use geographical coordinates.
11) TZ - I want to specify the time zone using the Posix TZ format.
#? 4
Please select a country whose clocks agree with yours.
 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) Beijing Time
2) Xinjiang Time
#? 1

The following information has been given:

	China
	Beijing Time

Therefore TZ='Asia/Shanghai' will be used.
Selected time is now:	Mon Jul 19 16:18:43 CST 2021.
Universal Time is now:	Mon Jul 19 08:18:43 UTC 2021.
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

2、配置:/etc/profile 环境变量文件

可以看出上述一顿猛如虎的操作无非就是干一件事情,生成一句话: TZ='Asia/Shanghai'; export TZ ,生成后需要将这句话复制粘贴到你的 /etc/profile 中,操作如下:

sudo vim /etc/profile

编辑完系统环境变量配置文件后使用source /etc/profile重新加载配置文件

3、删除localtime文件

sudo rm /etc/localtime

4、连接到上海时区文件

sudo ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

再次查看时区,验证已经生效成东八区时区

[aroot@APP2 ~]$ date -R
Mon, 19 Jul 2021 16:46:50 +0800
