Hi,


and what filesystem have your server???

maybe this parameter from man rsync helps you:

--modify-window
               When comparing two timestamps, rsync treats the 
timestamps as  being equal  if they differ by no more than the 
modify-window value.  This is normally 0 (for an exact match), but you 
may find  it  useful  to set  this to a larger value in some situations. 
  In particular, when transferring to or from an MS Windows FAT 
filesystem  (which  represents times with a 2-second resolution), 
--modify-window=1 is useful (allowing times to differ by up to 1 second).

I saw the above behaviour backing up a NTFS filesystem too (instead of FAT)

so try adding the parameter with =1 or =2 solve your problem,

so I don't remember if the above behaviour is present when the two 
machines have differents time (one of them don't have a ntp running or 
it didn't work properly) (different timezone is fine but the time maybe 
isn't accurate in his respective timezone)
