Centos system modification time

By default, the system uses the US time instead of the China time. You need to modify the system's time zone to change the current time of the system.

Log on to the system as a root user

Copy the corresponding time zone file, replace the centos System Time Zone file, or create a link file.
CP/usr/share/zoneinfo/$ main Time Zone/$ Time Zone/etc/localtime
Available in China:
CP/usr/share/zoneinfo/Asia/Shanghai/etc/localtime

Then reboot restarts the system. After restart, run the date command to check whether the current time of the system has changed to the current time in China.
