To change the time zone settings:

1. Go to the Center Server client and access the DSVA console.
2. Press ALT + F2 to open the non-graphical interface.

   This opens the command line interface (CLI).

3. Switch to root by executing the command below:

   sudo -s

4. Enter the default password "dsva".
5. Back up the old time zone settings. Run the following command:

   cp /etc/localtime /etc/localtime-old

6. Go to the directory /usr/share/zoneinfo. Run the following commands:

   cd /usr/share/zoneinfo
   ls -a

   The list of time zone regions will be displayed.

7. Choose the most appropriate region and replace the /etc/localtime file.

   For example, to set the local time in Shanghai, run the following command:

   cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

8. To verify that the time zone has been set, run the "date" command.
