Add - DateTime stamp when user added video to his/her favorites - YouTube - Issue 110 - gdata-issues - Google Code
http://code.google.com/p/gdata-issues/issues/detail?id=110#c24
Holy crap - this bug is fixed? If so, it means that YouTube favorites feeds now reflect when a video was made favorite, not when the video itself was changed. "For V2 the atom:published and atom:updated reflect the time the favorite was added. There is a new tag inside of called that gives the datetime that the video was uploaded."
