You can add this to Roam using {{[[roam/js]]}}
Grab the code in youtube-timestamps.js
and drop it in a javascript code block:
```javascript```
You can have timestamps at the beginning of any nested block. H:MM:SS
You can use the ctrl+shift+y
hotkey (currently assumes you have Roam42 installed, let me know if you'd prefer I drop that requirement) to grab the current timestamp of the video you're cursor is nested under and add it to the beginning of your block.
