+= Schedule Expression (Cronograma Expressão)
+
+Neste exemplo, exercitamos o `TimerService`.
+____
+``A interface TimerService fornece componentes de bean corporativo com
+acesso ao serviço de cronômetro fornecido pelo contêiner. O EJB Timer Service permite que os beans de entidade, os beans de sessão sem estado e os beans controlados por mensagem sejam registrados para eventos de retorno de chamada do cronômetro em um tempo especificado, após um tempo decorrido especificado ou após um intervalo especificado.''
+____
+
+Para uma descrição completa do TimerService, consulte o tutorial Java EE dedicado ao
+http://docs.oracle.com/javaee/6/tutorial/doc/bnboy.html[Timer Service].
+
+== FarmerBrown
+
+No `PostConstruct`, criamos 5 temporizadores programáticos. Provavelmente, os quatro primeiros não serão acionados durante a execução do teste; no entanto, o último terá o tempo limite esgotado algumas vezes.
+
+Cada cronômetro contém um atributo de informação, que pode ser inspecionado no tempo limite.
