Hi, I'm having a problem with my unit tests when running them in JavaScript. I'm using TimeZone.of("Europe/Amsterdam"), but that is not recognized during unit tests in JS (a IllegalTimeZoneException is thrown), presumably because it can't find some asset/resource with time zone information? Is this a known issue, does anyone know how to solve this?
The time zone can be found without problem when I run the code normally

It's likely that you need to require the npm package with js-joda timezones in tests. We do it this way in our tests: https://github.com/Kotlin/kotlinx-datetime/blob/v0.2.0/core/js/test/JsJodaTimeZoneModule.kt
and we're also adding the following npm dependency:

That fixed it indeed, thank you so much!
