Begin not working

[git-santosh]

below code is not working

 let url = 'http://www.youtube.com/watch?v=WKsjaOqDXgg';
 let video = ytdl(url,{begin:2});
 //let video = ytdl(url,{begin:'00:02:00.000'});
// let video = ytdl(url,{begin:'2ms'});
 video.pipe(fs.createWriteStream('video2.mp4'));

I have given try on passing different parameters on begin option but neither of them is not working for me

The begin option is unreliable

from readme

This option may not work on super short (less than 30s) videos, and has to be at or above 6s, see #129. It may also not work for some formats, see #219.
