Faked timestamps are not uncommon, but I've never heard of somebody faking a transfer speed using fake timestamps. If anybody could point to a prior example, I'd certainly appreciate it. I wonder what other data can be extracted from that as well: like the file copy algorithm used for the transfer (the the files copied alphabetically, shallow, deep, etc)?
