The forecast near the bottom of the widget uses correct time zones for OWM, but not met.no. At about 12pm EST, for example, the widget shows a forecast for 3pm in NYC when using OWM but does not for met.no. The date labels on the met.no forecast are also wrong; the one in the screenshot lists Tue 20 twice. I suspect it's related to some kind of incorrect conversion to or from UTC, as the widget is 5 hours off, e.g. the widget's forecast for 9pm matches yr.no at 4pm. The bug is not affected by the timezone choice in the widget settings, or by changing the timezone associated with the location (though both settings do affect the meteogram).
