I use ntp on all my systems, so I've never seen that message. Anyway, it occurred to me that simply picking a file on the client that is getting backed up repeatedly and doing a stat on it might be informative if the problem is time or timestamp related: Stat shows you the mtime, ctime, and atime (among other things):
