I'm not sure I follow the use case for Kotlin's

Duration

it seems to be missing

.between

? So I need to use Java's, in which case I can't use Kotlin's because importing both doesn't work? What am I missing?

you can

import x as y

to get around the name conflict locally

oh, and call kotlin's version something else?

either or both, right

it doesn't look like Kotlin's Duration will convert to a java Duration.

@TwoClocks you might want to use kotlinx-datetime. You'll get all you need, including

operator fun Instant.minus(Instant): Duration

to do

thisTime - thatTime

.

@Didier Villevalois thanks! I was not aware of this library. It solves all of my problems.
