MarketSeries.OpenTime Bug

Maybe I am bugging, but suspect something is wrong here, the MarketSeries.OpenTime does never seem to be a Friday. Please advise if this is expected or if I made an incorrect assumption about the OpenTime value?

Code:

On the Dax it gives the following output

Thanks.

            //Print(MarketSeries.OpenTime.LastValue.Date.DayOfWeek + " " + MarketSeries.OpenTime.LastValue.Date.ToShortDateString());
            if (MarketSeries.OpenTime.LastValue.DayOfWeek == DayOfWeek.Sunday)
            {
                Print("Trading Sunday");
            }

            {
