If you copy a file the modification time is preserved, but the change
time is the time you copied it.
Example:
At 10:54 I created file1, at 10:56 I copied it to file2:
$ ls -l file?
-rw-rw-rw-   1 user      user             5 Feb  8 10:54 file1
-rw-rw-rw-   1 user      user             5 Feb  8 10:54 file2
$ ls -lc file?
-rw-rw-rw-   1 user      user             5 Feb  8 10:56 file2
-rw-rw-rw-   1 user      user             5 Feb  8 10:54 file1
$ stat file?
  File: "file1"
  Size: 5            Filetype: Regular File
  Mode: (0666/-rw-rw-rw-)  Uid: (  501/    user)  Gid: (  501/  user)
Device:  3,6   Inode: 109772    Links: 1
Access: Tue Feb  8 10:56:09 2000(00000.00:00:11)
Modify: Tue Feb  8 10:54:50 2000(00000.00:01:30)
Change: Tue Feb  8 10:54:50 2000(00000.00:01:30)
 
  File: "file2"
  Size: 5            Filetype: Regular File
  Mode: (0666/-rw-rw-rw-)  Uid: (  501/   user)  Gid: (  501/  user)
Device:  3,6   Inode: 109791    Links: 1
Access: Tue Feb  8 10:54:50 2000(00000.00:01:30)
Modify: Tue Feb  8 10:54:50 2000(00000.00:01:30)
Change: Tue Feb  8 10:56:09 2000(00000.00:00:11)
$


So:
1) if rsync support "change time" instead of "modification time", use
it.
2) otherwise, you can write a script that sets the modification time of
files = their change time (by touching -t, for instance), right before
rsyncing.
3) maybe you can find a simpler way to do it :-)
