Formatting System.currentTimeMillis()

Question

I am trying to format the following time to hh:mm:ss:

long elapsed;
elapsed = ((System.currentTimeMillis() - startTime) / 1000);

What is the way for doing this?

You can use Androids version of DateFormat:

DateFormat.format("hh:mm:ss", elapsed);

Note that elapsed should be in milliseconds, so you should remove the /1000.

if we're talking about elapsed time, better using `kk` in place of `hh`, or 0 hrs will be shown as 12. – bigstones Aug 26 '12 at 17:25

Try this,

long elapsed;
elapsed = ((System.currentTimeMillis() - startTime) / 1000);

String display = String.format("%02d:%02d:%02d", elapsed / 3600, (elapsed % 3600) / 60, (elapsed % 60));
System.out.println(display);

And let me know what happen..

I suggest you use SimpleDateFormat for that? From that page an example with multiple formats:

 String[] formats = new String[] {
   "yyyy-MM-dd",
   "yyyy-MM-dd HH:mm",
   "yyyy-MM-dd HH:mmZ",
   "yyyy-MM-dd HH:mm:ss.SSSZ",
   "yyyy-MM-dd'T'HH:mm:ss.SSSZ",
 };
 for (String format : formats) {
   SimpleDateFormat sdf = new SimpleDateFormat(format, Locale.US);
   System.err.format("%30s %s\n", format, sdf.format(new Date(0)));
   sdf.setTimeZone(TimeZone.getTimeZone("UTC"));
   System.err.format("%30s %s\n", format, sdf.format(new Date(0)));
 }
