Installed 4.3.1 (1099)
When there are files with dates before Jan 1, 2011 on the remote directory these are being displayed as MMM DD, 2011 and when you bring them across to a local directory they are being time stamped with the future date. If I check the same site using FileZilla or other clients the dates are ok. I belive this is a windowing issue where dates in future should be assumed to be last year.
I belive the remote server is running Unix which normally shows dates like 'Dec 12' in the long display and not 'Dec 12 2010' unless they are more than 12 months old.
The remote directory in WinSCP looks like:
201012310400000.txt 7,982 12/31/2011 12:46:00 AM rw-r-r-- 110
In psftp it looks like:
-rw-r--r-- 1 110 110 7982 Dec 31 03:46 2010123104000000.txt
