Sometime in the past few years I have had an error when moving files between computers, and many of my personal files have incorrect modified time stamps (in some cases showing that files were created many years later than they actually were). I must have had a badly formed rsync command and/or failed to take into account the potential problems of copying between Linux and Windows, or some other foolish mistake.
I have just found an old backup of some of these files which has the original time information intact. Is there a way to transfer these times from the backup files without simply re-copying the files? As they have already been uploaded to Dropbox etc I'd rather not waste time uploading them all over again, but it would be nice to have the right information on the files.
The files live on an NTFS drive accessible to both Linux (Korora at the moment) and Windows 7, so a solution for either OS will be fine.
