Introdução
O indicador apresentado abaixo exibe o fuso horário atual no painel superior. A maneira como funciona é bastante simples. As configurações de fuso horário são definidas no arquivo /etc/timezone . Tudo o que o indicador faz, é ler esse arquivo e atualizar as informações exibidas, se necessário.
Salve o código-fonte abaixo como ~/bin/timezone_indicator , execute chmod +x ~/bin/timezone_indicator para torná-lo executável e execute como ~/bin/timezone_indicator . Se você deseja que ele comece cada vez que você se autenticar automaticamente, abra o menu Startup Applications, e adicione o caminho completo para o indicador como um dos comandos lá.
