Subject [jira] [Commented] (NET-635) Problems with German summertime
Date Mon, 27 Mar 2017 15:59:41 GMT


Sebb commented on NET-635:

I'm not sure what the issue is here.
What does NET do? What should it do instead?

Looks to me more like a problem with the FTP server which has allowed a file to be created
with an invalid timestamp.
Remember it is the server that generates the listing; if it generates an invalid timestamp
that is not an error in NET.

Also if you are concerned about timestamps, it would be better to use FTPClient.mlistFile()
or mdtmFile().
However not all servers support MLIST and MDTM.
