I think u can better tar the files , ftp it and untar it at the other end ... and the timestamp would be preserved ... try this way ... i guess this wud be better than changing the timestamp manually
When I FTP GET the file from my (tp) trading partner's server the files are not in tar format. The only access I have to my tp's server is ftp. So I cannot really tar my tp's file. I will ask my tp to tar the file before I FTP GET it. But what if my tp does not want to tar the file? What should I do?
