Sylvain Lebresne commented on CASSANDRA-7925:
---------------------------------------------

bq. If the user specifies a time stamp though it will collide on the server

What do you mean by that? That is, what method are you referring to that would 
allow a user to provide a timestamp that would conflict with a server side uuid?

> TimeUUID LSB should be unique per process, not just per machine

>  lsb collisions are also possible serverside.
> a sufficient solution would be to include references to pid and classloader 
> within lsb.
