I don't think I have seen MC get the [Date Created] field wrong when importing a file. I guess it is possible though.
Check that your Date Created is actually correct on the files with problems in Windows Explorer before trying a fix. Make sure you aren't looking at the Date Modified in Windows, or one of the other dates.
As Date Created is a system date set and maintained by Windows, you can't edit it in MC. If it appears that MC has the incorrect [Date Created] for some files, confirm they are correct in Windows, and then you could try to fix them in MC by selecting the problem files, right-clicking on them, and selecting "Update Library (from tags)". Of course, that will update all tags from the files, so you might lose some field edits in MC. So be sure that is what you want to do. Or perhaps even better, run the "Update tags (from Library)" function first so that the MC values are written to the files, and then "Update Library (from tags)". MC won't update the file's Date Created, so the value in the file itself should remain. Running both processes should fix an incorrect [Date Created] field value in MC.
But before I did anything like the above, I would want to be very sure that the files actually had the correct Date Created in Windows. It is more likely that some other application has changed the Date Created, and MC has just picked up the new date. A file backup or synchronisation program may change the Date Created and cause this issue, for example.
