Quick query - do people with good experience of both tend to use java.time or kotlin.time?

What do you value? kotlinx is still in alpha.... :shrug:

Is it? It's in `kotlin.time` not `kotlinx.time`, and annotated as `@WasExperimental` which suggests it isn't any more

aha - ok. sorry :slightly_smiling_face: - was thinking it was the external lib

I think they have very different use cases - `kotlin.time` is for benchmarks

<https://kotlinlang.org/docs/time-measurement.html>

<https://github.com/Kotlin/kotlinx-datetime> is marked as experimental

java.time, but that's because I know it. kotlinx one just seemed to have gaps or wrong concepts for me, but maybe it was just different.

And detecting timeouts, but yes, I see, and I see the confusion with kotlinx.time which looks much more familiar to a java.time user. Thanks all, helped me learn.

No, it's for logging events and timeouts. kotlinx-benchmark is for benchmarks

I've been using kotlin.time.Duration when declaring a duration such as `5.seconds` and then converting to a java duration when necessary. The main reason is I think the api for declaring the duration is a lot cleaner and more readable.
