标签:websevne   timezone   时区   tzselect   timeconfig   

1.查看系统时区:

方法1:

[root@mytest2 ~]# date -R

Sun, 07 Sep 2014 23:10:23 -0400

方法2:

[root@mytest2 ~]# cat /etc/sysconfig/clock 

# The ZONE parameter is only evaluated by system-config-date.

# The timezone of the system is defined by the contents of /etc/localtime.

ZONE="America/New_York"

UTC=true

ARC=false


2.修改系统时区:

方法1:使用tzselect


[root@mytest2 ~]# 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

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:      Mon Sep  8 11:19:54 CST 2014.

Universal Time is now:  Mon Sep  8 03:19:54 UTC 2014.

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

[root@mytest2 ~]# 


方法2:使用timeconfig(仅限于RedHat Linux和CentOS)


方法3:复制相应的时区文件,替换系统时区文件;或者创建链接文件

cp /usr/share/zoneinfo/$主时区/$次时区 /etc/localtime

例如:在设置中国时区使用亚洲/上海(+8)

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

修改/etc/sysconfig/clock为相应的配置:

[root@mytest2 Asia]# cat /etc/sysconfig/clock 

# The ZONE parameter is only evaluated by system-config-date.

# The timezone of the system is defined by the contents of /etc/localtime.

ZONE="Asia/Shanghai"

UTC=true

ARC=false

3.将修改后的信息写入hwclock.

hwclock -w

4.验证:

hwclock

date -R
