When a file is scp to a remote server, the time stamp of the file in remote server will be changed and hence the file will be created with new date and time.

When we rsync a file or a folder, time stamp will also be copied to new server.

ie. when a file created on jan 1st is moved to a remote server using rsync, then the remote server will show Jan 1st as the file creation date and not the new date.
