[Q#8237193][A#24182811] How to convert currentTimeMillis to a date in Java?

https://stackoverflow.com/q/8237193

I have milliseconds in certain log file generated in server, I also know the locale from where the log file was generated, my problem is to convert milliseconds to date in specified format. The processing of that log is happening on server located in different time zone. While converting to "SimpleDateFormat" program is taking date of the machine as such formatted date do not represent correct time of the server. Is there any way to handle this elegantly ? Output:

Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(timeStamp);

int mYear = calendar.get(Calendar.YEAR);
int mMonth = calendar.get(Calendar.MONTH);
int mDay = calendar.get(Calendar.DAY_OF_MONTH);

  public static int[] fromMillsToDate(long timeStamp) {
    Calendar calendar = Calendar.getInstance();
    calendar.setTimeInMillis(timeStamp);
    int out[] = new int[3];
    out[0] = calendar.get(Calendar.YEAR);
    out[1] = calendar.get(Calendar.MONTH);
    out[2] = calendar.get(Calendar.DAY_OF_MONTH);
    return out;
