Rationale for Timestamps in .cast format

I’m struggling to edit some cast files and wondering why the timestamp is an offset to the beginning. For editing it would be much easier to just record the timestamp to the previous frame and in general that would make more sense (to me :slight_smile:

I’m wondering if I’m missing something obvious or if the absolute timestamp is only historical baggage…

Sorry if this has been discussed a million times… new to asciinema and super excited about it!
