The default time zone of the GCS is the time zone you chose when creating the image. If it is necessary to modify, see this section and change it to the required local time or another time zone on the network.

The operation of changing the time zone is slightly different for different Linux operating systems. This section takes CentOS 6.x 64bit as an example to introduce the operation of changing the time zone of the Linux GCS.

Log in to GCS;
Execute the following command to switch to the root account; su - root
Execute the following command to query the supported time zones;

ls /usr/share/zoneinfo/

Wherein, the "/user/share/zoneinfo" directory shows the directory structure of time zone data files. You can find the file of your required time zone through this directory structure, as shown in the following figure:

The information shown in the figure is partly time zone and partly directory. Wherein, the directory contains the time zone files for specific cities. You can find the time zone of the city to be used for the GCS in this directory.

For example: Assume that you need to use the time zone where Hong Kong is located, the time zone file directory

is/usr/share/zoneinfo/Hongkong.

If you need to use the time zone where Paris of France is located, you need to execute the command ls /usr/share/zoneinfo/Europe first to open the directory. The time zone file directory is "/usr/share/zoneinfo/Europe/Paris".

Set a new time zone;
Execute the following command to open the "/etc/sysconfig/clock" file.

vim /etc/sysconfig/clock

Find the ZONE item, and change it to the file name of the required time zone.

For example:

Assuming that it is changed to the time zone where Hong Kong is located, the ZONE item needs to be changed to: ZONE="Hongkong"
Assuming that it is changed to the time zone where Paris is located, the ZONE item needs to be changed to: ZONE="Europe/Paris"
Press ESC, execute the following command, save and exit the file;

Execute the following command to check whether the "/etc/localtime" file already exists in the GCS;

ls /etc/localtime

If yes, perform 7; if no, jump to 8.

Execute the following command to delete the existing "/etc/localtime" file;

rm /etc/localtime

Execute the following command to create a symbol link between "/etc/localtime" and the time zone file, so that the GCS can find the time zone file when referencing local time information;

ln -sf /usr/share/zoneinfo/Hongkong /etc/localtime

Execute the following command to restart the system so that all services and applications accept the new time zone information;

reboot

Log in to the GCS again, use the root account to execute the following command, query the time zone of the GCS, and confirm whether the change is successful;

ls -lh /etc/localtime
