I can’t remember who it was that was asking on the fediverse about parcing likes from Twitter in some sort of a useable format with dates, but I am here to tell whoever it was that the reason we can’t do this is because Twitter does not include so much as a unix timestamp in the like.js file contained in your archive, which is also why we can’t sort from oldest to newest in the HTML renderer. All you get is the text and expanded archive.
Welp so much for that project.
