Description

I use cassandra driver java to do some insert operation.I notice that Cassandra Java Driver use client-side timestamp as default.

I make my client server one hour ahead than my cassandra server,then i insert some record to an exist table and use sstable2json tool to check my record ' s timestamp.

i find out that if i insert a record with ifnotexist,the record's timestamp used server-side timestamp,otherwise it use client-side timestamp.

I think this is a very strange result.
