code: public String toFfmpegString()
  	{
  		final long hours = this.hours + (24 * this.days);
  
  		return String.format("%02d:%02d:%02d.%06d", hours, minutes, seconds, getFramesPartAsMicroseconds());
  	}
docs: Returns the timecode in FFmpeg format. The format of the timecode is hh:mm:ss:uuuuuu (where u = microseconds). The hours
  component counts days as well (i.e. <code>01:01:01:01:00</code> will be encoded as <code>25:01:01.000000</code>)
