Configuring Settings.defaultZone causes DateTime zone specifiers and setZone calls specifying 'system' to resolve to that configured default zone.

Автор образца записал здесь то, чего ожидал бы разработчик или модель. Контракт ниже — это то, что действительно выполнялось.

When Settings.defaultZone is overridden, Info.normalizeZone('system') and DateTime.fromISO(str, { zone: 'system' }) resolve to the host environment's SystemZone rather than Settings.defaultZone, while 'default' resolves to Settings.defaultZone instead of creating an invalid DateTime.
Info.normalizeZone('system') equals SystemZone.instance and does not equal Settings.defaultZone when defaultZone is changed
Info.normalizeZone('default') equals Settings.defaultZone and is valid
DateTime.fromISO with zone 'system' produces a valid DateTime with zoneName equal to SystemZone.instance.name rather than Settings.defaultZone
DateTime.fromISO with zone 'default' produces a valid DateTime with zoneName equal to Settings.defaultZone
DateTime#setZone('system') resets zone to SystemZone.instance.name while DateTime#setZone('default') resets zone to Settings.defaultZone
