Yes, if you like to put it that way but intentionally. The second case was
used for debugging purposes. I wanted the amount of data to be reduced and
thus chose one subdirectory only.

drwxr-xr-x 48 2005-09-24 12:39 tagesbackup_differentiell_2005-09-24/
drwxr-xr-x 568 2005-09-24 03:11 tagesbackup_differentiell_2005-09-24_/
lrwxrwxrwx 51 2005-09-24 03:03 ziel
-> /backup/novell/tagesbackup_differentiell_2005-09-24

That's part of the content of my backup directory. A script creates a
subdirectory and sets the symlink "ziel" to it so that the rsync call does
not have to care about the directory name (it is in another script).

In order to demonstrate the problem I have renamed the original directory
(to *_) for that day and created a new one. Please note thate the mtime of
that original directory is that of it's creation an not that of the rsync
source directory:

ls -ld /mnt/novellserver/SYS
drwxr-xr-x 1 root root 512 1985-12-31 23:00 /mnt/novellserver/SYS

That's on a netware volume but that should not make any difference I think.

Now I run rsync for the subdirectory PUBLIC:
drwxr-xr-x 296 2005-09-08 17:47 tagesbackup_differentiell_2005-09-24

The mtime of the target directory is changed to the one of the source
directory:

ls -ld /mnt/novellserver/SYS/PUBLIC
drwxr-xr-x 1 root root 512 2005-09-08 17:47 /mnt/novellserver/SYS/PUBLIC

I don't see any reason for once changing the mtime and once leaving it
untouched. It's not a real problem for me, I am just curious if that's a
bug (triggert by whatever). :-)

Right. It points to the empty directory
tagesbackup_differentiell_2005-09-24 in the same directory in both cases.
The commands are not run one after another with the same directory/target.

I would not see the sense in this action but the point is: Both cases
behave differently!
