HappyFox allows you to set the "Timezone" and "Language" settings, which will be set to every new agent added to your support system.

Change Time and Language settings:

• Login to your Agent interface and navigate to Manage >> Account Settings. 
• Under the Basic Settings, you can choose your time zone from the Default Time Zone drop-down box.
• Choose the language from the Default Language drop-down box. Once you are done, click on Save Settings button, to record your changes.

In cases where a specific agent works from a different timezone or requires a different language setting, such personal preferences can be set by going into My Settings from the agent panel.
