Somewhere in the past the timestamp format returned by windows/the windows ftp server changed.
In the past the timestamp had a format like: '09-21-10 06:00PM'.
The 'current' format however is: '09-21-10 18:00'.
In version 1.4 this resulted in no files being displayed because parsing the timestamp fails;
In version 2 this results in the files being displayed but without the timestamp.
(This is the result of change 645299)
The attached patch updates the code so that it detects both the old and the new format of the timestamp.
A bug that also mentions this, or at least the comments, https://issues.apache.org/jira/browse/NET-50
