There is also a way to set rsync to use 1 second granularity (--modify-window=1). I think there might be a way to edit the default settings the NAS uses to include this - but am not sure. mdgm likely knows. It's also possible that frontview backup already uses this with rsync - there are similar problems with different versions of linux, including the linux used in OS6 and OS4.
Alternatively you could probably write a simple script to truncate the timestamps on the ReadyNAS volume, and put that in a cron job. If it runs before the backup, then the timestamps would match (after an initial sync).
ext4 format will also work (using your existing job), and will be faster than ntfs. ext3 will not. Though as mgdm says, using ext4 requires formatting/data loss (and also means you need ext support on whatever machine might be used to restore the backups or verify them).
