I need to know `elapsedNow()` from a time point that I receive from an api...

How about just using regular `Instant` class from Java time API? That should work.

Kotlin time support is still experimental, and from what I can see there's no easy way of calculating a duration from an arbitrary timestamp =(

Yup, that's what it seems like... wonder why they left this out? People using multiplatform could get stuck with this... also testing seems to be easier since there's `TestClock` for that...
