How Do I Convert System.currentTimeMillis To Time Format? (HH:MM:SS) [duplicate]

Question

I am trying to convert System.currentTimeMillis to current time format of (hh:mm:ss). So far this is what I've tried and it's not working right.

    Long currentTime = System.currentTimeMillis();

    int hours;
    int minutes;
    int seconds;

    String getSecToStr = currentTime.toString();
    String getTimeStr = getSecToStr.substring(8,13);

    seconds = Integer.parseInt(getTimeStr);

    minutes = seconds / 60;
    seconds -= minutes * 60;

    hours = minutes / 60;
    minutes -= hours * 60;

    String myResult = Integer.toString(hours) + ":" + Integer.toString(minutes) + ":" + Integer.toString(seconds);

    System.out.println("Current Time Is: " + myResult);

Any ideas? Much appreciated!

Answer 1

There are some object that you can use to make this more easy, like SimpleDateFormat and Date.

First prepare the time in mills:

Long currentTime = System.currentTimeMillis();

Choose your desier format with SimpleDateFormat:

SimpleDateFormat simpleDateFormat = new SimpleDateFormat("hh:mm:ss");

Create your date object:

Date date = new Date(currentTime);

Apply that format into your date object:

String time = simpleDateFormat.format(date);

Log it:

Log.d(TAG, "onCreate: " + time);

Result:

17:05:73
