I would assume that I'd only need to give a formatted date/time none UTC as the Longitude and Latitude should produce it's unique timezone??? My API call https://weatherkit.apple.com/api/v1/weather/en/${latitude}/${longitude}?dataSets=currentWeather&currentAsOf=${date}&timezone=${timeZone} timezone is listed as a required query param in the api. Do I need it or not? It returns a result with or without the param. If I don't pass one, then what is the returned weather data?
