Hi guys! 🙂

There is a way to serialize with @Serializable a java.util.Date with this format 2018-11-14T13:25:30Z ? I´m using Ktor and kotlinx.serialization

Use a custom serializer as described here: https://github.com/Kotlin/kotlinx.serialization/blob/master/docs/serializers.md#serializing-3rd-party-classes

But instead of converting the date to a long & vice versa, you convert it to the ISO 8601 string and back.

If you don't specifically need a java.util.Date (which are soft-deprecated anyways):

Untitled.kt

Oops, that's also got an extension:

fun String.toInstantOrNull(): Instant? = runCatching { Instant.parse(this) }.getOrNull()
