If I am checking wind velocity for a country other than where I am, are the dates/times given in my local time?

Like the new version so far. Not so much a problem of version, probably more a met modelling problem in our NZ and Pacific area but as both a pilot and sailor I find the sea forecasts underdo the wind speed by at least 5 kts in general and quite often 10kts. I've just learned to always add at least 5 at sea. E.g today wind forecast for now is 16kts approx both models. Actual wind is 26kt.
