    // Get elapsed time in seconds
    float elapsedTimeSec = elapsedTimeMillis / 1000F;

    // Get elapsed time in minutes
    float elapsedTimeMin = elapsedTimeMillis / (60 * 1000F);

    // Get elapsed time in hours
    float elapsedTimeHour = elapsedTimeMillis / (60 * 60 * 1000F);

    // Get elapsed time in days
    float elapsedTimeDay = elapsedTimeMillis / (24 * 60 * 60 * 1000F);
  }
