SimpleDateFormat is not parsing the milliseconds correctly

Question

Background:

In my database table, I have two timestamps

timeStamp1 = 2011-08-23 14:57:26.662
timeStamp2 = 2011-08-23 14:57:26.9
         


        

Answer 1

I'd suggest using Joda-Time. It handles these situations properly. In the following example, the milliseconds are correctly parsed as 200ms.

import org.joda.time.DateTime;
import org.joda.time.format.DateTimeFormat;
import org.joda.time.format.DateTimeFormatter;

public class ParseMillis {

  public static void main(String[] args) {
    String s = "00:00:01.2";
    DateTimeFormatter format = DateTimeFormat.forPattern("HH:mm:ss.S");
    DateTime dateTime = format.parseDateTime(s);
    System.out.println(dateTime.getMillisOfSecond());
  }
}
