You are right. On second thought it is more obvious that st_ctime is  
*not* changed because the inode pointing to the directory is changed  
on move, not the directory inode itself i guess. So maybe the OP has  
done a "mv" across mount points? On what filesystem was this behaviour  
observed by the way?
