Hey, does anyone know how I can parse 2022-05-20T19:36:27Z with kotlinx-datetime?

Do it manually? ISO 8601 is pretty straightforward. Substring+toInt will get you very far. Even regex will work.

"2010-06-01T22:19:44.475Z".toInstant()

? https://github.com/Kotlin/kotlinx-datetime#converting-instant-and-local-datetime-to-and-from-string

even better. i guess when it's always UTC you don't need a timezone database!

All hail UTC.

I am trying to use it with kotlinx serialization to serialize a Json response body. What I ended up doing was just parsing it to string when receiving the object and then parsing it to LocalDateTime using "".toInstant() later. I Don't know if this is the best/most corrrect way to do it though. Maybe I should write a custom serializer that parses it correctly when receiving the body? Thanks for the tip @Richard Gomez.

A custom serializer is the way to go

Yeah, I expected as much. I just write a custom serializer and annotate the field with @Serializable(with = MyCustomSerializer) then?

kotlinx-datetime includes serializers (https://github.com/Kotlin/kotlinx-datetime/blob/master/core/common/src/serializers/InstantSerializers.kt) so you likely only need to annotate the property with

@Serializable(with = InstantIso8601Serializer::class)

@phldavies That works! Thanks a lot :)
