Hora em milisegundo

Programação Java
#1

Opa! Tem como acrescentar mais um nível de horário no Java? Tipo, uso um getTimeInstance para pegar a hora, mas quero que mostre também os milisegundos. Tem como fazer isso? Valeu!

#2

Cara existe a class GregorianCalendar:

http://java.sun.com/j2se/1.4.2/docs/api/java/util/GregorianCalendar.html

System.out.println("HOUR: " + calendar.get(Calendar.HOUR));
 System.out.println("HOUR_OF_DAY: " + calendar.get(Calendar.HOUR_OF_DAY));
 System.out.println("MINUTE: " + calendar.get(Calendar.MINUTE));
 System.out.println("SECOND: " + calendar.get(Calendar.SECOND));
 System.out.println("MILLISECOND: " + calendar.get(Calendar.MILLISECOND));

[]s

Para obter o tempo corrente e imprimir corretamente…

try {
java.util.Date atual = new java.util.Date();
java.text.SimpleDateFormat formater = new java.text.SimpleDateFormat("dd/MM/yyyy hh:mm:ss,SSS);
System.out.println ( formater.format ( atual ) ) ;
} catch (Exception e) {
e.printStackTrace();
}

Boa sorte.

System.currentTimeMilis() te retorna a data em milesegundos.
