ListDirectoryDetails Date issue

[JHine]

C# issue with ListDirectoryDetails.
Has anyone seen a case where the detail listing of files strips out the year of the create date? In most cases the Month, Day and Year are displayed, however, I have come across a case with previously working code where the Year is not being displayed and instead the time is.

string[] dirSeperator = { "\r\n" };
            string[] dirList = reader.ReadToEnd().Split(dirSeperator, StringSplitOptions.RemoveEmptyEntries);

normal results:
1259530 Sep 07 2012 File.csv

new results:
1259530 Sep 18 00:29 File.csv
