I am not sure what to do for KotlinJS, and how it relates to those 2 functions.

[spand]

For js in the browser there are Date.getTime() and https://developer.mozilla.org/en-US/docs/Web/API/Performance

[spand]

Not sure if you need more than that

[simon.vergauwen]

Alright, that also point to that there is no alternative for getTimeNanos or CLOCK_MONOTONIC in Js.

[spand]

Well, javas is pretty much best effort also:

This method provides nanosecond precision, but not necessarily
     * nanosecond resolution (that is, how frequently the value changes)
     * - no guarantees are made except that the resolution is at least as
     * good as that of {@link #currentTimeMillis()}.

[simon.vergauwen]

Yes, I am aware of that. It depends a lot on the underlying system, which is fine.

[simon.vergauwen]

I am working on a Clock abstraction for Arrow. Some other MPP languages (or frameworks in languages) I checked offer both since nanos is better suited for tracking timed events compared to millis.

[simon.vergauwen]

I was wondering if Kotlin had already thought out something for this issue.

Jetbrains is working on a mpp date-time thing iirc

[simon.vergauwen]

Ah awesome thanks! Any references would be appreciate, can’t seem to find anything

[ribesg]

Last time I heard about it it was more of a plan I think, I’m not sure. There were also talks about a mpp file lib

[fcosta]

You can use this library for mpp projects: https://github.com/korlibs/klock

[ribesg]

That works but I don’t like its API

[simon.vergauwen]

Thanks for the reference @fcosta. I'll check the sources of that repo :)

[bashor]

in Kotlin/JS you can write something like js("Date").now() or window.performance.now()

[bashor]

for window you need import kotlin.browser.window

[simon.vergauwen]

@bashor awesome! thanks for the response
