The code below gives me the current time. But it does not tell anything about milliseconds.

Answer 1

java.text (prior to java 8)

public static ThreadLocal dateFormat = new ThreadLocal() {
    protected DateFormat initialValue() {
        return new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");
    };
};

...
dateFormat.get().format(new Date());

java.time

public static DateTimeFormatter dateTimeFormatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSS");

...
dateTimeFormatter.format(LocalDateTime.now());
