Solutionfile .sln is the changedate the creationdate?

Question

I've got a little project im coding.
And i didn't document the date i started it.
Can i be sure that the date of change of the solution file (.sln) is the creationdate?
Or do the solutionfile change while developing?
And if yes , when?
Or is there a other way i can read this in Visual Studio 2010, e.g. at the properties of that project?

You can't be sure if the date of change is the creation data as with each file.

E.g if you add projects to your solution and save it, the date of change, is changed. But i think if you go to the files properties there is a creation date.
