FTP set date/time

I’m using SyncBackSE to synchronize some media files between my personal computer and my dreamhost site over FTP. For SyncBack to really synchronize properly, once it copies files from my PC to dreamhost, it needs to be able to set the date/timestamp of the new file to match the last modified time of the file on my PC. Otherwise when I next try to synchronize, the time on the dreamhost file is newer, and SyncBack thinks the files are out of sync. Is there a way to specify in the dreamhost settings that a ftp client should be able to set/modify file timestamps? Thanks for any help or suggestions.
