It’s simple really. If you want to send your friend a youtube video and have it start playing at a certain time into the video. YouTube has a link for that…
Just copy the YouTube URI as usual, and append:
&t=1m24s
to the end of it (where “1m42s” is the time you want your video to start playing at).
So the whole URL would look something like this:
http://www.youtube.com/watch?v=Bqxnm6t3QMw&t=0m42s
Just an example, don’t judge me.
