I meant where do the timestamp begin? Depending on the definition of "begin" you may have issues with different editions of the same movie.
I.e. if in the same episode Netflix adds it's own logo and Amazon doesn't, then 00:01:35 will point to different scenes depending if you're watching Netflix vs Amazon
You're definitely correct. Not even only on different streaming services. Movies have different cuts too. For instance, Blade Runner has 5 different cuts
