Milliseconds and nanoseconds in time format

Question

This is my code:

long currentTime = System.currentTimeMillis();
Date date = new Date(currentTime); // if you really have long
String result = new SimpleDateF         


        

Answer 1

String result = new SimpleDateFormat("HH:mm:ss:SSS").format(date);

"HH:mm:ss:SSS" //SSS stands for milliseconds
