If all timestamps that I receive from an API in my application use a non ISO 8601 extended format, is there a way I can globally use a custom serializer anywhere I use `Instant`, or do I have to annotate it with `Contextual` / `Serializable(with)` on every occurrence?

<https://kotlinlang.org/api/kotlinx.serialization/kotlinx-serialization-core/kotlinx.serialization/-use-serializers/|@UseSerializers> is per-file

This would be project wide though. Multiple files across multiple modules.

I guess I could use a value type that wraps Instant :thinking_face:

in my work project, we have a custom Android Lint rule with autofix to add `@file:UseSerializer(...)` if the use sites weren't annotated, and it seems to work well enough for us

yeah it's not quite global, but it's easier than the alternatives

> I guess I could use a value type that wraps Instant :thinking_face:
```typealias MyInstant = @Serializable(with = xxx) Instant```
works, it doesn't need to be a full custom type
