If my memory is right, we were just asking for the latitude and longitude, so it may very well be the case that without timezone it defaults to UTC (which makes sense because daytimeForecast starting 7Z is actually the evening in Australia). As far as I can tell the documentation says that the timezone can be a string? What kind of string? Like "Australia/Melbourne", "AEDT", "UTC+10", any of the above? And how would I work that into the URL of my query? Thanks!
