/usr/share/zoneinfo/asia/saves the system's various time zone information

/etc/localtime Save current system time zone and time information

[email protected] ~]# CP/usr/share/zoneinfo/asia/shanghai/etc/localtime
Cp:overwrite '/etc/localtime '? Y
[[Email protected] ~]# Date
Wed Jul 602:20:03 CST2016     //Change to CST
[Email protected] ~]# date-r
Wed Jul 6 02:21:45 +0800
Then reset the time.

A more humane approach can be modified by commands in the RH system:
[[Email protected] ~] #tzselect         //Tzselect–select a time zone

Follow the prompts to enter the Select item carriage return!
