可以使用命令 tzselect,修改时区。操作示例:
[root@localhost ~]# tzselect

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.

#? 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 Jul 19 22:05:59 CST 2016.
Universal Time is now: Tue Jul 19 14:05:59 UTC 2016.
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
通过修改配置文件修改时区
也可以直接通过修改配置文件来变更时区。
vi /etc/sysconfig/clock
ZONE=Asia/Shanghai(查/usr/share/zoneinfo下面的文件)
rm /etc/localtime
ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
[root@localhost zoneinfo]# ll /etc/localtime
-rw-r--r--. 1 root root 2819 Jun 29 2015 /etc/localtime
[root@localhost zoneinfo]# cat /etc/sysconfig/clock
ZONE="America/Los_Angeles"
UTC=true
ARC=false
[root@localhost ~]# cd /usr/share/zoneinfo
[root@localhost zoneinfo]# ll
