Wrong days titles in forecast?

[unspacyar]

Hello. I am noticing that apparently, the weekday titles (in the forecast section) are incorrect. Since the last version from past year, I noticed that the forecast is usually not correct, and I realized that probably is just the weekday that is "one day before" the right one.

I am attaching a picture of Weather, and as a comparative, AnsiWeather. Notice that on Weather, I guess the forecast starting in "Sunday". But is already Mondays. This is reflected properly in the Ansiweather application. Also, if we replace the "Sunday" with "Monday" and go on, the rest of the forecast kind of match with Ansiweather.

Hope my explanation makes sense for you. Sorry, my english is not very good.
