Getting date to show as it is in scatter chart

Set up a pivot table to summarize data and then to get a scatter chart out of it I copied and pasted it as values. So far so good...
However I have brought in the dates, tweaked them and my Revised Date column is looking like a date but alas is not quacking like the proper date in the scatter chart I created from it. The dates are all showing up as 1900 dates instead of the dates as given...even though the dates look like dates. What am I missing here. (Scatter chart is right at end of the data)

Thanks as always. :-)
