The server timezone is normally changing via the command line of the server. But it is simply possible to do it from the WHM panel itself if the server is installed with a WHM panel. You can watch the video tutorial by clicking on this link. Here I am providing the steps to do it via the panel.
- Log in to WHM panel as root.
- You can find the 'Server Time' option from the 'Server Configuration' section in WHM.
- There you can find a dropdown with a huge list of available timezones. You can select the required one and press the 'Change Timezone' button.
- It is recommended to reboot the server after the change.
