I am using your latest build of Aspose.Tasks 22.214.171.124
I have included two sample .mpp and .xml files. When I open the files in the .mpp format I get "1/1/0001" as the datetime from Aspose.Tasks.Project.CurrentDate and Aspose.Tasks.Project.StatusDate. But when I open the files in the .xml format I get the correct datetime. Not sure if there is something that I am not setting up correctly in the file. I have opened the ProjectvInformation and changed the dates but still getting the same problem.
