It's going to depend on the implementation and the system. The implementation will probably end up needing to define a time zone provider, which will ultimately be provided by host/system hooks provided to Temporal from the engine implementation.

Temporal.Duration.prototype.toLocaleString will end up using Intl.DurationFormatter though, so that will ultimately be what he wants (probably going to depend on that ICU4X implementation being complete though).
