.ietf.org/html/draft-ietf-ldup-model-09. The CSN syntax is :
```
             ::=  #  #  #        ::= A GMT based time, YYYYmmddHHMMSS.uuuuuuZ     ::= [000000-ffffff]        ::= [000-fff]  ::= [000000-ffffff] 
```
It distinguishes a change made on an object on a server, and if two operations take place during the same timeStamp, the operation sequence number makes those operations distinct. @author Apache Directory Project
