Retrieving DateTime x-axis value from Chart control

I have a chart control with a data in it. The x-axis data is of DateTime and the Y-axis is an integer. I'm trying to pull the data out of the graph and export it to excel, but the DateTime values aren't coming out in a way I can understand them or figure out how to decode them. Example values are as such: The graph begins at 4/30/2012 and goes to 8/13/2012. The values show: ``` {X=41030, Y=16991} {X=41031, Y=34363} {X=41032, Y=26744} {X=41033, Y=28180} {X=41034, Y=17478} ...intermediate values {X=41134, Y=1785} ``` I set the chart x-axis type to date time with ``` RestartBooksAttempts.Series["Attempts"].XValueType = ChartValueType.DateTime; RestartBooksAttempts.Series["Books"].XValueType = ChartValueType.DateTime; ``` and I'm grabbing the values with: ``` Convert.ToDateTime(chart.Series[s.Name].Points[i].XValue) double y = chart.Series[s.Name].Points[i].YValues[0]; ``` obviously the x-points are not a DateTime convertable value, does anyone have any idea how to decode these values?
