Yes.  createTimestamp and creatorsName tell you when the entry was 
created and by whom.  There are also modifyTimestamp and modifiersName.  
Note that these are operational attributes, so you have to ask for them 
explicitly on the ldapsearch command line or in an LDAP search request - 
they are not returned by default with the other regular attributes.

If you're just looking for new entries, createTimestamp will probably 
work.  If you need more than that, such as is provided by the Active 
Directory DirSync control, you might want to investigate the Retro 
Changelog feature.
