NET-83 added an option to allow dates to be up to 1 day in the future, but this is not the default.
This means that FTP will assume the wrong year when listing recent files which are on servers with a clock which is ahead of the client.
This includes servers in a different timezone (unless the user specifies the server timezone) - e.g. client in US listing files on a server in the UK.
As far as I can tell, Unix servers use short dates for dates within about +/- 6 months of the current date, so this should not cause any
problems. But of course it is possible that some servers use short dates for past dates only.
The behaviour of FTP parsing is likely to be improved overall by changing the default to allow dates up to 1 day into the future.
