Dale Lee commented on NET-573:
------------------------------

Am getting the same issue as the original cloned ticket. I have tried using 
both commons-net-2.2.jar and commons-net-3.3.jar with AS400 ftp.

When I use the command java -jar commons-net-examples-3.3.jar FTPClientExample 
-l X.X.X.X <username> <password> /reports
Below is what I get:
ZFTPDEV          9069 05/20/15 15:36:52 *STMF

I do see the timestamp value when using FTPFile.getRawListing() and 
FTPFile.toString(). But when I use FTPFile.getTimestamp(), the timestamp 
returns null. 

Is this an known issue with AS400 server? I have validated the timestamp 
configured matches the time listed in rawlisting.

> The LIST command which is used internally in the FTPClient retrieves the 
> timestamps successfully. However after parsing the FTPFile has a null value 
> for the timestamp field.
> The null value is returned just when a user place the file in the AS400 usint 
> the NetServer Servivice. This is used to share foldes between windows network 
> and the AS/400
> Please help us fix this problem. It is not critical to us.
