String.toInstant throws exception on macosx64, but not jvm

Got a DateTimeFormatException when converting a string value which was produced on jvm. to an Instant on macosx64

// jvm

val instantString = Clock.System.now().plus(Int.MAX_VALUE.days).toString()
instantString.toInstant() // << does not throw

println(instantString)
// +5881633-11-04T10:51:10.025414219Z

// macosx64
"+5881633-11-04T10:51:10.025414219Z".toInstant() // << throws DateTimeFormatException

Native and JS support a much smaller range of years than JVM, namely years ±1000000 at most, instead of ±1000000000 for the JVM. We didn't consider dates outside the smaller range to be useful in practice.

The only values that are guaranteed to work across all platforms are those between Instant.DISTANT_PAST and Instant.DISTANT_FUTURE.

Yes, that is what I ended up using in the event the addition operation exceeded Instant.DISTANT_FUTURE on jvm so that conversion on macosx64 works.

I see now it is documented on Instant.DISTANT_FUTURE, will close this issue as it's "expected" behavior.
