Try this:

Date date = new Date(logEvent.timeSTamp);DateFormat formatter = new SimpleDateFormat("HH:mm:ss.SSS");formatter.setTimeZone(TimeZone.getTimeZone("UTC"));String dateFormatted = formatter.format(date);

See SimpleDateFormat for a description of other format strings that the class accepts.

See runnable example using input of 1200 ms.

long millis = durationInMillis % 1000;long second = (durationInMillis / 1000) % 60;long minute = (durationInMillis / (1000 * 60)) % 60;long hour = (durationInMillis / (1000 * 60 * 60)) % 24;String time = String.format("%02d:%02d:%02d.%d", hour, minute, second, millis);

I'll show you three ways to (a) get the minute field from a long value, and (b) print it using the Date format you want. One uses java.util.Calendar, another uses Joda-Time, and the last uses the java.time framework built into Java 8 and later.

The java.time framework supplants the old bundled date-time classes, and is inspired by Joda-Time, defined by JSR 310, and extended by the ThreeTen-Extra project.

The java.time framework is the way to go when using Java 8 and later. Otherwise, such as Android, use Joda-Time. The java.util.Date/.Calendar classes are notoriously troublesome and should be avoided.

java.util.Date & .Calendar

final long timestamp = new Date().getTime();// with java.util.Date/Calendar apifinal Calendar cal = Calendar.getInstance();cal.setTimeInMillis(timestamp);// here's how to get the minutesfinal int minutes = cal.get(Calendar.MINUTE);// and here's how to get the String representationfinal String timeString =    new SimpleDateFormat("HH:mm:ss:SSS").format(cal.getTime());System.out.println(minutes);System.out.println(timeString);

Joda-Time

// with JodaTime 2.4final DateTime dt = new DateTime(timestamp);// here's how to get the minutesfinal int minutes2 = dt.getMinuteOfHour();// and here's how to get the String representationfinal String timeString2 = dt.toString("HH:mm:ss:SSS");System.out.println(minutes2);System.out.println(timeString2);

Output:

09:24:10:254
