Subject [jira] Commented: (NET-159) FTPFile.getTimestamp() is off by one year

Hi Julien,

Thank you for your early response.

The ftp server I am dealing with is not in my control; I have asked for more 
information on it.

I do get a note in the startup message that they are using "X2 WS_FTP Server 
5.0.5 (3295908506)".

I downloaded an evaluation copy of the "WS FTP" server and was able to 
reproduce the year problem on my local network. I did not change any 
configuration on the FTP server (left the default installation configuration 
set by WS FTP). So the answer to your second question about specifying a 
Date format in a FTPConfig would be "No".

I installed WS FTP on a server with a FAT32 disk; running Windows 2000 SP4.

The dir listing on the server does not return the year information for files 
created in the current year:
And being on the local network, the server and JVM are in the same timezone. 
However, it appears that the FTP server is reporting the UT time, which is 
ahead of the local time by 6 hrs.

For debugging, I played around with the time on the server and touching the 
test file - and indeed the year is reported as the previous year if the time 
on the file timestamp is in the future compared to time of the client 

Enabling the option to list file time in local time helped the issue. So did 
setting the timezoneid for the FTP server that is not under my control. 
However, this does mean that the year would be off by one if the Server time 
is ahead of the actual time by a few minutes. Isn't it possible to assume 
that the year on the file is the current year (based on the timezone of the 
server - so the year is not skewed around new year's or for recent files) at 
the server location; if the year is not included in the listing?

For now, my issue is resolved, so thank you very much for your help.

Please let me know if you need more information.
