SKM YaBB Newbies Offline Posts: 2	milliseconds and tenths of seconds Nov 17th, 2008, 5:22pm   Hi, I need a little help if its not too much trouble. Does anyone know how to get tenths of seconds and milliseconds out of processing? I'm trying to make a clock that shows these values as well as hours, minutes and seconds. If anyone can post a speedy reply to this I'd be very grateful. Thanks Si

If so, you may want to check out System.currentTimeMillis() (http://java.sun.com/j2se/1.5.0/docs/api/java/lang/System.html#currentTimeMillis() ). Hope this helps.

Re: milliseconds and tenths of seconds Reply #3 - Nov 17th, 2008, 8:36pm   I guess the following shall do the trick: Quote: import java.text.DateFormat; import java.text.SimpleDateFormat; import java.util.Calendar; DateFormat formatter = new SimpleDateFormat("dd/MM/yyyy hh:mm:ss.SSS"); // // Get date and time information in milliseconds // long now = System.currentTimeMillis(); // // Create a calendar object that will convert the date and time value // in milliseconds to date. We use the setTimeInMillis() method of the // Calendar object. // Calendar calendar = Calendar.getInstance(); calendar.setTimeInMillis(now); System.out.println(now + " = " + formatter.format(calendar.getTime())); The formatter string basically would determine what part of the actual timestamp is output so if you don't need the actual date and just need the time, you can get rid of the dd/MM/yyyy part.
