If our server was running in China, then we would use the "Asia/Shanghai" time zone:

rm -rf /etc/localtime
ln -s /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
You can navigate to the directory /usr/share/zoneinfo to find the appropriate time zone. There is an excellent resource on Wikipedia for timezone listings.

Input date again, you will find that the local system time has changed to CST (China Standard Time) GMT+0800.

Next, we will write the system time info into the hardware clock.

vi /etc/sysconfig/clock
Modify the content of this file as below.

ZONE="Asia/Shanghai"
UTC=false
ARC=false
