Working in different countries or having to work in a multilingual environment requires your computer to be set up to support this. Use the YaST language and timezone modules to install additional system languages and adjust the country and timezone settings accordingly. The YaST language module also lets you change your system language or determine a primary language that you use most often. Install secondary languages to get optional localizations if you need to start applications or desktops in languages other than the primary one. The YaST timezone module allows you to adjust your country and timezone settings and synchronize your system clock against a time server.
