How to detect or count a course launch or resume ?

Thanks Matthew, I found a solution capturing current date/time in JavaScript. Still need more testing.

There is no difference of time (in seconds) between a trigger to jump to a slide and the timeline start of that slide. However, when the course is resumed, even quickly after closing it, there is a difference of at least a second. That's how I know the course has been resumed.

There might be a more elegant way of detecting when a course is resumed 🤔
