How to get current time in YYYY-MM-DD HH:MI:Sec.Millisecond format in java

Question

The below code gives me current time. but it does not tell anything about millisecond

public static String getCurrentTimeStamp() {
      SimpleDateFormat sdfDate = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");//dd/MM/yyyy
      Date now = new Date();
      String strDate = sdfDate.format(now);
      return strDate;
}

I get date in the format 2009-09-22 16:47:08 (YYYY-MM-DD HH:MI:Sec)

But I want to retrieve current time in the format 2009-09-22 16:47:08.128 ((YYYY-MM-DD HH:MI:Sec.Ms)

where 128 tells the millisecond.

SimpleTextFormat will work fine. Here the lowest unit of time is second. but I want millisecond also.

Answer 1

You only have to add the millisecond field in your date format string:

new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");

The API doc of SimpleDateFormat describes the format string in detail.

Answer 2

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");

Answer 3

Here you go:

 GregorianCalendar now = new GregorianCalendar();//gets the current date and time
 int year = now.get(Calendar.YEAR);
 int month = now.get(Calendar.MONTH);
 int day = now.get(Calendar.DATE) + 1; //add one because January is integer 0
 int hour = now.get(Calendar.HOUR_OF_DAY);
 int minute = now.get(Calendar.MINUTE);
 int second = now.get(Calendar.SECOND);

 String output = year + "-" + month + "-" + day+ " " + hour + ":" + minute + ":" + second;
